Ali

Ali's father, Abu Talib ibn Abd al-Muttalib, was the custodian of the Ka'bah and a sheikh of Banu Hashim, an important branch of the powerful Quraysh tribe. He was also an uncle of Muhammad, and had raised Muhammad after Abd al-Muttalib, Abu Talib's father and Muhammad's grandfather, died.[19][20] Ali's mother, Fatima bint Asad, also belonged to Banu Hashim, making Ali a descendant of Isma'īl (Ishmael), the firstborn son of Ibrahim (Abraham).[21] Many sources, especially Shia ones, attest that Ali was born inside the Ka'bah in the city of Mecca,[1][22] where he stayed with his mother for three days.[1][23] His mother reportedly felt the beginning of her labour pain while visiting the Kaaba and entered it where her son was born. Some Shia sources contain miraculous descriptions of the entrance of Ali's mother into the Kaaba. Ali's birth in the Kaaba is regarded as a unique event proving his "high spiritual station" among Shia, while Sunni scholars consider it a great, if not unique, distinction.[5]

According to a tradition, Muhammad was the first person whom Ali saw as he took the newborn in his hands and Muhammad named him Ali, meaning "the exalted one". Muhammad had a close relationship with Ali's parents. When Muhammad was orphaned and later lost his grandfather Abd al-Muttalib, Ali's father took him into his house.[1] Ali was born two or three years after Muhammad married Khadijah bint Khuwaylid.[24] When Ali was five years old, Muhammad took Ali into his home to raise him. Some historians say that this was because there was a famine in Mecca at the time and that Ali's father had a large family to support; however, others point out that feeding Ali would not have been a burden on his father, as Ali was five years old at the time and, despite the famine, Ali's father, who was financially well-off, was known for giving food to strangers if they were hungry.[25] While it is not disputed that Muhammad raised Ali, it was not due to any financial stress that Ali's father was going through.

Many Shia Muslims also celebrate Imam Ali's birth anniversary (13th day of Rajab) as Father's Day in Iran.[26] The Gregorian date for this changes every year:

Ali had been living with Muhammad and his wife Khadija since he was five years old. When Ali was nine, Muhammad announced himself as the Prophet of Islam, and Ali became the first male to accept Islam in Muhammad's presence, and the second person after Khadija. According to Sayed Ali Asgher Razwy in A Restatement of the History of Islam & Muslims, "Ali and [the] Qur'an 'grew up' together as 'twins' in the house of Muhammad Mustafa and Khadija-tul-Kubra."[30]

The second period of Ali's life began in 610 when he declared Islam at the age of 9, and ended with the Hijra of Muhammad to Medina in 622.[1] When Muhammad reported that he had received a divine revelation, Ali, then only about nine years old, believed him and professed to Islam.[1][2][31][32][33] Ali became the first male to embrace Islam.[34][35][36][37] Shia doctrine asserts that in keeping with Ali's divine mission, he accepted Islam before he took part in any old Meccan traditional religious rites, regarded by Muslims as polytheistic (see shirk) or paganistic. Hence the Shia say of Ali that his face is honoured, as it was never sullied by prostrations before idols.[31] The Sunnis also use the honorific Karam Allahu Wajhahu, which means "God's Favour upon his Face." The reason his acceptance is often not called a conversion is because he was never an idol worshipper like the people of Mecca. He was known to have broken idols in the mould of Abraham and asked people why they worshipped something they made themselves.[38] Ali's grandfather, along with some members of the Bani Hashim clan, were Hanifs, or followers of a monotheistic belief system prior to the emergence of Islam in Mecca.

Muhammad invited people to Islam in secret for three years before he started inviting them publicly. In the fourth year of his preaching, when Muhammad was commanded to invite his close relatives to come to Islam,[39] he gathered the Banu Hashim clan in a ceremony. At the banquet, he was about to invite them to Islam when Abu Lahab interrupted him, after which everyone left the banquet. The Prophet ordered Ali to invite the 40 people again. The second time, Muhammad announced Islam to them and invited them to join.[40] He said to them:

I offer thanks to Allah for His mercies. I praise Allah, and I seek His guidance. I believe in Him and I put my trust in Him. I bear witness that there is no god except Allah; He has no partners; and I am His messenger. Allah has commanded me to invite you to His religion by saying: And warn thy nearest kinsfolk. I, therefore, warn you, and call upon you to testify that there is no god but Allah, and that I am His messenger. O ye sons of Abdul Muttalib, no one ever came to you before with anything better than what I have brought to you. By accepting it, your welfare will be assured in this world and in the Hereafter. Who among you will support me in carrying out this momentous duty? Who will share the burden of this work with me? Who will respond to my call? Who will become my vicegerent, my deputy and my wazir?[41]

Ali was the only one to answer Muhammad's call. Muhammad told him to sit down, saying, "Wait! Perhaps someone older than you might respond to my call." Muhammad then asked the members of Banu Hashim a second time. Once again, Ali was the only one to respond, and again, Muhammad told him to wait. Muhammad then asked the members of Banu Hashim a third time; Ali was still the only volunteer. This time, Ali's offer was accepted by Muhammad. Muhammad "drew [Ali] close, pressed him to his heart, and said to the assembly: 'This is my wazir, my successor and my vicegerent. Listen to him and obey his commands.'"[42] In another narration, when Muhammad accepted Ali's eager offer, Muhammad "threw up his arms around the generous youth, and pressed him to his bosom" and said, "Behold my brother, my vizir, my vicegerent...Let all listen to his words, and obey him."[43] Upon hearing this, the sons of Abd al-Muttalib departed from the feast, mocking Muhammad's words, as they scoffed at Abu Talib ibn Abd al-Muttalib, "He has ordered you to listen and obey your son!".[44]^:17 In Tarikh ut-Tabari and as-Seerat ul Halabiyya, it has been recorded that Abu Talib asks his son Ali, "What is this belief you are following?" to which Ali replies, "Father, I have believed in Allah and His Messenger, and have given credence to him, kept to him, and followed him."[44]

Sir Richard Burton writes about the banquet in his 1898 book, saying, "It won for [Muhammad] a proselyte worth a thousand sabers in the person of Ali, son of Abu Talib."[45]

During the persecution of Muslims and boycott of the Banu Hashim in Mecca, Ali stood firmly in support of Muhammad.[46]

In 622, the year of Muhammad's migration to Yathrib (now Medina), Ali risked his life by sleeping in Muhammad's bed to impersonate him, thereby thwarting an assassination attempt and ensuring Muhammad's escape.[1][31][47] This night is called Laylat al-Mabit. According to some ahadith, a verse was revealed about Ali concerning his sacrifice on the night of Hijra which says "And among men is he who sells his nafs (self) in exchange for the pleasure of Allah."[48][49]

Ali survived the plot, but risked his life again by staying in Mecca to carry out Muhammad's instructions: to restore to their owners all the goods and properties that had been entrusted to Muhammad for safekeeping. Ali then went to Medina with Fatimah bint Asad (his mother), Fatimah bint Muhammad (Muhammad's daughter), and two other women.[2][31]

Ali was 22 or 23 years old when he migrated to Medina. When Muhammad was creating bonds of brotherhood among his companions, he selected Ali as his brother, claiming that "Ali and I belong to the same tree, while people belong to different trees."[2][31][50][44] For the ten years that Muhammad led the community in Medina, Ali was extremely active in his service as his secretary and deputy, serving in his armies, the bearer of his banner in every battle, leading parties of warriors on raids, and carrying messages and orders.[51] As one of Muhammad's lieutenants, and later his son-in-law, Ali was a person of authority and standing in the Muslim community.[52]

With the exception of the Battle of Tabouk, Ali took part in all battles and expeditions fought for Islam.[31] As well as being the standard-bearer in those battles, Ali led parties of warriors on raids into enemy lands.

Ali first distinguished himself as a warrior in 624 at the Battle of Badr. The battle began with Ali defeating the Meccan champion Walid ibn Utba; one historian described Ali's opening victory at the battle as "the signal of the triumph of Islam."[53] Ali also killed many other Meccan soldiers in the battle—according to Muslim tradition, between twenty and thirty-five, with most agreeing on twenty-seven,[54] while all the other Muslims combined killed another twenty-seven.[55]

Ali played a major role in the Battle of Uhud, as well as many other battles, where he wielded a bifurcated sword known as Zulfiqar.[56] He had the special role of protecting Muhammad when most of the Muslim army fled from the battle of Uhud,[1] and it was said Lā fitā illā ʿAliyy, lā sayfa illā Dhul-Fiqār (لَا فِتَی إِلَّا عَلِيّ، لَا سَيْفَ إِلَّا ذُو ٱلْفِقَار, (There is) no brave youth except Ali, there is no sword (which renders service) except Zulfiqar).[57] He commanded the Muslim army in the Battle of the Trench, where he defeated the legendary Arab warrior Amr ibn Abd al-Wud.[58] Muhammad made Ali commander at this battle, claiming that "I will hand the standard to a man who loves Allah and His Messenger and is loved by Allah and His Messenger. He will come back with conquest."[44] Following this battle Muhammad gave Ali the name Asadullāh (which means "Lion of God") and reportedly praised him, saying "Ali's strike on Amr ibn Abd al-Wud is greater than the worship of both mankind and jinn until the Day of Judgement."[44] Ali also defended Muhammad in the Battle of Hunayn in 630.[1]

Sherira Gaon (c. 906–c. 1006) describes in a responsum how that the head of the Jewish community in Peroz-Shapur (now al-ʾAnbār), a community numbering some 90,000, warmly welcomed Ali ibn Abi Talib when he marched with his army into the country and conquered it, and how that he received them with a friendly disposition.[59]

Muhammad designated Ali as one of the scribes who would write down the text of the Quran, which had been revealed to Muhammad during the previous two decades. As Islam began to spread throughout Arabia, Ali helped establish the new Islamic order. He was instructed to write down the Treaty of Hudaybiyyah, the peace treaty between Muhammad and the Quraysh, in 628. Ali was so trustworthy that Muhammad asked him to carry the messages and declare the orders. In 630, Ali recited to a large gathering of pilgrims in Mecca a portion of the Quran that declared Muhammad and the Islamic community no longer bound by agreements made earlier with Arab polytheists. During the Conquest of Mecca in 630, Muhammad asked Ali to guarantee that the conquest would be bloodless. He ordered Ali to break all the idols worshiped by the Banu Aus, Banu Khazraj, Tayy, and those in the Kaaba to purify it after its defilement by the polytheism of old times. Ali was sent to Yemen one year later to spread the teachings of Islam. He was also known for settling several disputes and putting down the uprisings of various tribes.[1][2]

According to hadith collections, in 631, an Arab Christian envoy from Najran (currently in northern Yemen and partly in Saudi Arabia) came to Muhammad to argue which of the two parties erred in its doctrine concerning 'Isa (Jesus). After likening Jesus' miraculous birth to Adam's creation,[60] Muhammad called them to mubahala (conversation), where each party should bring their knowledgeable men, women and children, and ask God to curse the lying party and their followers.[61] Muhammad, to prove to them that he was a prophet, brought his daughter Fatimah, 'Ali and his grandchildren Hasan and Husayn. He went to the Christians and said "this is my family" and covered himself and his family with a cloak.[62] According to Muslim sources, when one of the Christian monks saw their faces, he advised his companions to withdraw from Mubahala for the sake of their lives and families. Thus the Christian monks vanished from Mubahala. According to Allameh Tabatabaei's Tafsir al-Mizan, the word "Our selves" in this verse[61] refers to Muhammad and Ali. Then he narrates that Imam Ali al-Rida, eighth Shia Imam, in discussion with Al-Ma'mun, Abbasid caliph, referred to this verse to prove the superiority of Muhammad's progeny over the rest of the Muslim community, and considered it proof of Ali's right to the caliphate due to God having made Ali like the self of Muhammad.[63]

The Investiture of Ali, at Ghadir Khumm (MS Arab 161, fol. 162r, 1307/8 Ilkhanid manuscript illustration)

As Muhammad was returning from his last pilgrimage in 632, he made statements about Ali that are interpreted very differently by Sunnis and Shias.[1] He halted the caravan at Ghadir Khumm, gathered the returning pilgrims for communal prayer and began to address them.[64]

According to the Encyclopedia of Islam:

Taking Ali by the hand, he asked of his faithful followers whether he, Muhammad, was not closer (awlā) to the Believers than they were to themselves; the crowd cried out: "It is so, O Apostle of God!"; he then declared: "He of whom I am the mawla, of him Ali is also the mawla (man kuntu mawlāhu fa-ʿAlī mawlāhu)".[65][66]

Shias regard these statements as constituting the designation of Ali as the successor of Muhammad and as the first Imam; by contrast, Sunnis take them only as an expression of close spiritual relationship between Muhammad and Ali, and of his wish that Ali, as his cousin and son-in-law, inherit his family responsibilities upon his death, but not necessarily a designation of political authority. [18] [67] Many Sufis also interpret the episode as the transfer of Muhammad's spiritual power and authority to Ali, whom they regard as the wali par excellence.[1][68]

Sources, among them both Shia and Sunni, state that, after the sermon, Abu Bakr, Umar, and Uthman pledged allegiance to Ali.[69][70][71] However, there have been doubts regarding the veracity of the tradition due to evidence that Ali may not have been present during the sermon, instead being in Yemen at the time—a view held by the historian Ibn Kathir.[72]

The next phase of Ali's life started in 632, after the death of Muhammad, and lasted until the assassination of Uthman ibn Affan, the third caliph, in 656. During those 24 years, Ali took no part in battle or conquest,[2] nor did he assume any executive position, instead withdrawing from political affairs, especially after the death of his wife, Fatimah Zahra. He used his time to serve his family and worked as a farmer. Ali dug a lot of wells and planted gardens near Medina and endowed them for public use. These wells are known today as Abar Ali ("Ali's wells").[73]

Ali compiled a complete version of the Quran, mus'haf,[74] six months after the death of Muhammad. The volume was completed and carried by camel to show to other people in Medina. The order of this mus'haf differed from that which was gathered later during the Uthmanic era. This book was rejected by several people when he showed it to them. Despite this, Ali made no resistance against the standardised mus'haf.[75]

While Ali was preparing Muhammad's body for burial and performing his funeral rites, a small group of approximately fourteen Muslims[76] met at Saqifah. There, Umar ibn al-Khattab pledged allegiance to Abu Bakr, who subsequently assumed political power. The gathering at Saqifah was disputed by some of Muhammad's companions, who held that Ali had been designated his successor by Muhammad himself.[33][77]

Relations between Abu Bakr and Ali may have become strained after this.[78] Following the gathering at Saqifa, Umar and his supporters were allegedly sent by the new Caliph to Ali's house where Ali, Fatimah, and some of their allies were gathered.[79] Several scholars, such as Al-Tabari and Ibn Qutaybah, relate that Umar threatened to burn the building down if Ali refused to acknowledge Abu Bakr's authority.[80][81][82] While the historian Al-Baladhuri states that the altercation never became violent and ended with Ali's compliance,[83] some traditions add that Umar and his supporters forcibly entered the house, resulting in Fatimah's miscarriage of their unborn son Muhsin.[84] The Kitab Sulaym ibn Qays (attributed to Sulaym ibn Qays, but possibly a much later creation)[85] concludes the incident with Ali being dragged out of the house with a rope tied around his neck.[86] These events have been disputed, with several early historical sources arguing that Fatimah's child Muhsin had died in early childhood rather than being miscarried. Other sources add that Ali later willingly offered Abu Bakr his oath of allegiance and gave a praise-filled oration during his funeral.[87][88] Professor Coeli Fitzpatrick surmises that the story of the altercation reflects the political agendas of the period and should therefore be treated with caution.[89]

Nevertheless, the issue of succession to Muhammad caused the Muslims to split into two groups, Sunni and Shia. Sunnis assert that even though Muhammad never appointed a successor, Abu Bakr was elected first caliph by the Muslim community. The Sunnis recognize the first four caliphs as Muhammad's rightful successors. Shias believe that Muhammad explicitly named Ali as his successor at Ghadir Khumm and Muslim leadership belonged to him by dint of divine order.[33]

According to Wilferd Madelung, Ali himself was firmly convinced of his legitimacy for the caliphate based on his close kinship with Muhammad, his knowledge of Islam, and his merits in serving its cause. He told Abu Bakr that his delay in pledging allegiance (bay'ah) to him was based on his belief in his own claim to the caliphate. Ali did not change his mind when he finally pledged allegiance to Abu Bakr and then to Umar and to Uthman but had done so for the sake of the unity of Islam, at a time when it was clear that the Muslims had turned away from him.[33][90] Ali also believed that he could fulfill the role of Imam without fighting.[91]

At the beginning of Abu Bakr's caliphate, there was a controversy about Muhammad's endowment to his daughter, especially the oasis of Fadak, between Fatimah and Ali on one side and Abu Bakr on the other side. Fatimah asked Abu Bakr to turn over their property, the lands of Fadak and Khaybar, but Abu Bakr refused and told her that prophets did not have any legacy and that Fadak belonged to the Muslim community. Abu Bakr said to her, "Allah's Apostle said, we do not have heirs, whatever we leave is Sadaqa." Together with Umm Ayman, Ali testified to the fact that Muhammad granted it to Fatimah Zahra, when Abu Bakr requested her to summon witnesses for her claim. Fatimah became angry and stopped speaking to Abu Bakr, and continued assuming that attitude until she died.[92] According to some sources, 'Ali did not give his oath of allegiance to Abu Bakr until some time after the death of his wife, Fatimah, in the year 633.[2]

He pledged allegiance to the second caliph, 'Umar ibn Khattab, and helped him as a trusted advisor. 'Umar particularly relied upon Ali as the chief judge of Medina. He also advised Umar to set Hijra as the beginning of the Islamic calendar. 'Umar followed 'Ali's suggestions in political matters as well as religious ones.[93]

'Ali was one of the electoral council to choose the third caliph which was appointed by 'Umar. Although 'Ali was one of the two major candidates, the council was inclined against him. Sa'd ibn Abi Waqqas and Abdur Rahman bin Awf, who were cousins, were naturally inclined to support Uthman, who was Abdur Rahman's brother-in-law. In addition, Umar gave the deciding vote to Abdur Rahman, who offered the caliphate to Ali on the condition that he should rule in accordance with the Quran, the example set by Muhammad, and the precedents established by the first two caliphs. Ali rejected the third condition while Uthman accepted it. According to Ibn Abi al-Hadid's Comments on the Peak of Eloquence Ali insisted on his prominence there, but most of the electors supported Uthman and Ali was reluctantly urged to accept him.[94]

'Uthman ibn 'Affan expressed generosity toward his kin, Banu Abd-Shams, who seemed to dominate him, and his supposed arrogant mistreatment toward several of the earliest companions such as Abu Dharr al-Ghifari, Abd-Allah ibn Mas'ud and Ammar ibn Yasir provoked outrage among some groups of people. Overt resistance arose in 650–651 throughout most of the empire.[95] The dissatisfaction with his rule and the governments appointed by him was not restricted to the provinces outside Arabia.[96] When Uthman's kin, especially Marwan, gained control over him, the noble companions, including most of the members of elector council, turned against him or at least withdrew their support, putting pressure on the caliph to mend his ways and reduce the influence of his assertive kin.[97]

At this time, 'Ali had acted as a restraining influence on Uthman without directly opposing him. On several occasions Ali disagreed with Uthman in the application of the Hudud; he had publicly shown sympathy for Abu Dharr al-Ghifari and had spoken strongly in the defence of Ammar ibn Yasir. He conveyed to Uthman the criticisms of other Companions and acted on Uthman's behalf as negotiator with the provincial opposition who had come to Medina; because of this some mistrust between Ali and Uthman's family seems to have arisen. Finally, he tried to mitigate the severity of the siege by his insistence that Uthman should be allowed water.[2]

There is controversy among historians about the relationship between Ali and Uthman. Although pledging allegiance to Uthman, Ali disagreed with some of his policies. In particular, he clashed with Uthman on the question of religious law. He insisted that religious punishment had to be meted out in several cases, such as those of Ubayd Allah ibn Umar and Walid ibn Uqba. In 650, during the pilgrimage, he reproached Uthman for his change of the prayer ritual. When Uthman declared that he would take whatever he needed from the fey', Ali exclaimed that in that case the caliph would be prevented by force. Ali endeavoured to protect companions such as Ibn Mas'ud from maltreatment by the caliph.[98] Therefore, some historians consider Ali one of the leading members of Uthman's opposition, if not the main one. But Wilferd Madelung rejects their judgment due to the fact that Ali did not have the Quraysh's support to be elected as a caliph. According to him, there is not even evidence that Ali had close relations with rebels who supported his caliphate, much less directed their actions. [99] Some other sources say Ali had acted as a restraining influence on Uthman without directly opposing him.[2] However, Madelung relates that Marwan told Zayn al-Abidin, the grandson of Ali, that "No one [among the Islamic nobility] was more temperate toward our master than your master."[100]

Uthman's assassination meant that rebels had to select a new caliph. This met with difficulties since the rebels were divided into several groups: the Muhajirun, Ansar, Egyptians, Kufans and Basrites. There were three candidates: Ali, Talhah and Al-Zubayr. First the rebels approached Ali and offered him the caliphate. Some of Muhammad's companions tried to persuade Ali to accept the office,[102][103][104] but he turned down the offer, requesting he be made a counsellor instead of a chief.[105] Talhah, Zubayr and other companions also refused the rebels' offer as well. Therefore, the rebels warned the inhabitants of Medina to select a caliph within one day, or they would take drastic action. In order to resolve the deadlock, the Muslims gathered in the Prophet's Mosque on 18 June 656, to appoint the caliph. Initially, 'Ali refused to accept the office, simply because his most vigorous supporters were rebels. However, when some notable companions of Muhammad, in addition to the residents of Medina, urged him to accept the offer, he finally agreed. According to Abu Mekhnaf's narration, Talhah was the first prominent companion who gave his pledge to 'Ali, but other accounts claimed otherwise, stating they were forced to give their pledge. Also, Talhah and Al-Zubayr later claimed they supported him only reluctantly. Regardless, Ali refuted these claims, insisting they recognised him as caliph voluntarily. Wilferd Madelung believes that coercion was not a factor and that they pledged publicly in the mosque.[13][14] While the overwhelming majority of Medina's population as well as many of the rebels gave their pledge, some important figures or tribes did not do so. The Umayyads, kinsmen of Uthman, fled to the Levant, or remained in their houses, later refusing 'Ali's legitimacy. Sa'ad ibn Abi Waqqas was absent and 'Abdullah ibn 'Umar abstained from offering his allegiance, but both of them assured 'Ali that they would not act against him.[13][14] Ali thus inherited the Rashidun caliphate – which extended from Egypt in the west to the Iranian highlands in the east—while the situation in the Hejaz and the other provinces on the eve of his election was unsettled.

Uthman had appointed his family members as governors and in other positions of power, and public dissatisfaction with this nepotism was one of the factors that had caused a rebellion against him.[106] In addition, Uthman's governors were widely known for their corruption and plundering. Soon after Ali became caliph, he dismissed Uthman's governors immediately, against the counsel of his advisers that it would not be politically wise to do so, as he refused to be complicit in their injustice and corruption.[107][108][109][110] According to Madelung, Ali was deeply convinced of his right and his religious mission, unwilling to compromise his principles for the sake of political expediency, and ready to fight against overwhelming odds.[111] Some of Uthman's governors were replaced, but others, such as Muawiyah I (a relative of Uthman and governor of the Levant), refused to submit to Ali's orders.[2]

When he was appointed caliph, Ali stated to the citizens of Medina that Muslim polity had come to be plagued by dissension and discord; he desired to purge Islam of any evil. He advised the populace to behave as true Muslims, warning that he would tolerate no sedition and those who were found guilty of subversive activities would be dealt with harshly.[112]

A'ishah, Talhah, Al-Zubayr and the Umayyads, especially Muawiyah I and Marwan I, wanted 'Ali to punish the rioters who had killed Uthman.[113][114] They encamped close to Basra. The talks lasted for many days and the subsequent heated exchange and protests during the parley turned from words to blows, leading to loss of life on both sides. In the confusion the Battle of the Camel started in 656, where Ali emerged victorious.[115] Some historians believe that they used this issue to seek their political ambitions because they found Ali's caliphate against their own benefit. The rebels maintained that Uthman had been justly killed, for not governing according to the Quran and Sunnah; hence, no vengeance was to be invoked.[2][31][116]

Some say the caliphate was a gift of the rebels and Ali did not have enough force to control or punish them,[112] while others say Ali accepted the rebels' argument or at least did not consider Uthman a just ruler.[117] Ali himself writes, in the Nahj al-Balagha, that he was blamed by the Umayyads for the assassination of Uthman.[118]

The Umayyads knowledge of me did not restrain them from accusing me, nor did my precedence in accepting Islam keep these ignorant people from blaming me. Allah's admonitions are more eloquent than my tongue. I am the contester against those who break away from Faith and the opposer of those who entertain doubts. Uncertainties should be placed before Qur'an, the Book of Allah (for clarification). Certainly, people will be recompensed according to what they have in their hearts. – Nahj al-Balagha: Sermon 75[118]

Under such circumstances, a schism took place which led to the first civil war in Muslim history. Some Muslims, known as Uthmanis, considered Uthman a rightful and just caliph till the end, who had been unlawfully killed. Some others, known as the party of Ali, believed Uthman had fallen into error, had forfeited the caliphate, and been lawfully executed for his refusal to mend his ways or step down; thus, Ali was the just and true Imam and his opponents were infidels. This was not the position of Ali himself. This civil war created permanent divisions within the Muslim community regarding who had the legitimate right to occupy the caliphate.[119]

The First Fitna, 656–661, followed the assassination of Uthman, continued during the caliphate of Ali, and was ended by Muawiyah's assumption of the caliphate. This civil war is regretted as the end of the early unity of the Islamic ummah (nation).[120]

Ali appointed 'Abd Allah ibn al'-Abbas[121] governor of Basra. Later, Muawiyah I, governor of the Levant and cousin of Uthman, refused Ali's demands for allegiance. Ali opened negotiations, but Muawiyah insisted on Levantine autonomy under his rule. Muawiyah mobilised an army and refused to pay homage to Ali on the pretext that his contingent had not participated in the election. Ali then moved his armies north and the two sides encamped at Siffin for more than one hundred days, most of the time being spent in negotiations. Although Ali exchanged several letters with Muawiyah, he was unable to dismiss the latter, nor persuade him to pledge allegiance. Skirmishes between the parties led to the Battle of Siffin in 657.[2][122]

A week of combat was followed by a violent battle known as laylat al-harir (the night of clamour). Muawiyah's army was on the point of being routed when Amr ibn al-As advised Muawiyah to have his soldiers hoist mus'haf (either parchments inscribed with verses of the Quran, or complete copies of it) on their spearheads in order to cause disagreement and confusion in Ali's army.[2][122] Ali saw through the stratagem, but only a minority wanted to pursue the fight.[33] The two armies finally agreed to settle the matter of who should be caliph by arbitration. The refusal of the largest bloc in Ali's army to fight was the decisive factor in his acceptance of the arbitration. The question as to whether the arbiter would represent Ali or the Kufans caused a further split in Ali's army. Ash'ath ibn Qays and some others rejected Ali's nominees, 'Abd Allah ibn 'Abbas and Malik al-Ashtar, and insisted on Abu Musa Ash'ari, for his neutrality. Finally, Ali was urged to accept Abu Musa. Amr ibn al-As was appointed by Muawiyah as an arbitrator. Seven months after the battle, in February 658, the two arbitrators met at Adhruh about 10 miles northwest of Maan in Jordan. Amr ibn al-As convinced Abu Musa Ash'ari that both Ali and Muawiyah should step down and a new caliph be elected. Ali and his supporters were stunned by the decision, which had lowered the caliph to the status of the rebellious Muawiyah. Ali was therefore outwitted by Muawiyah and Amr ibn al-As.[123][124] When the arbitrators assembled at Daumet-ul-Jandal, a series of daily meetings were arranged for them to discuss the matters in hand. When the time arrived for making a decision about the caliphate, Amr bin al-As convinced Abu Musa al-Ashari that they should deprive both Ali and Muawiya of the caliphate, and give the Muslims the right to elect the caliph. Abu Musa al-Ashari also concurred.[125] According to Poonawala, it seems that the arbiters and other eminent persons, with the exclusion of Ali's representatives, met in January 659 to discuss the selection of the new caliph. Amr supported Muawiyah, while Abu Musa preferred his son-in-law, Abdullah ibn Umar, but the latter refused to stand for election in default of unanimity. Abu Musa then proposed, and Amr agreed, to depose both Ali and Muawiyah and submit the selection of the new caliph to a Shura. In the public declaration that followed Abu Musa observed his part of the agreement, but Amr declared Ali deposed and confirmed Muawiya as caliph.[2]

Ali refused to accept this state of affairs and found himself technically in breach of his pledge to abide by the arbitration.[126][127][128] 'Ali protested that it was contrary to the Qur'an and the Sunnah and hence not binding. Then he tried to organise a new army, but only the Ansar, the remnants of the Qurra led by Malik Ashtar, and a few of their clansmen remained loyal.[2] This put Ali in a weak position even amongst his own supporters.[126] The arbitration resulted in the dissolution of 'Ali's coalition, and some have opined that this was Muawiyah's intention.[2][129]

The most vociferous opponents in Ali's camp were the very same people who had forced Ali into the ceasefire. They broke away from Ali's force, rallying under the slogan "arbitration belongs to God alone." This group came to be known as the Kharijites ("those who leave"). They considered everyone to be their enemy. In 659 Ali's forces and the Kharijites met in the Battle of Nahrawan.[125][130][131] The Qurra then became known as the Kharijites. The Kharijites then started killing Ali's supporters and other Muslims. They considered anyone who was not part of their group as an unbeliever.[131] Although 'Ali won the battle by a huge margin, the constant conflict had begun to affect his standing.[125] While dealing with the Iraqis, 'Ali found it hard to build a disciplined army and effective state institutions. He also spent a lot of time fighting the Kharijites. As a result, 'Ali found it hard to expand the state on its eastern front.[132]

At about the same time, unrest was brewing in Egypt. The governor of Egypt, Qais, was recalled, and Ali had him replaced with Muhammad ibn Abi Bakr (the brother of Aisha and the son of Islam's first caliph Abu Bakr). Muawiyah allowed 'Amr ibn al-'As to move against Egypt and 'Amr eventually conquered it for the second time in his career.[133] Amr had first taken Egypt eighteen years earlier from the Romans but had been dismissed by Uthman.[133] Muhammad ibn Abi Bakr had no popular support in Egypt and managed to muster 2000 men but they dispersed without a fight.[133]

In the following years, Muawiyah's army occupied many cities of Iraq, which Ali's governors could not prevent, and the people offered no support for a defense. Muawiyah overpowered Egypt, Hijaz, Yemen and other areas.[134] In the last year of Ali's caliphate, the mood in Kufa and Basra changed in his favour as the people became disillusioned with Muawiyah's reign and policies. However, the people's attitude toward Ali differed deeply. Just a small minority of them believed that Ali was the best Muslim after Muhammad and the only one entitled to rule them, while the majority supported him due to their distrust and opposition to Muawiyah.[135]

The connection between the Indus Valley and Shia Islam was established by the initial Muslim missions. According to Derryl N. Maclean, a link between Sindh and Shias or proto-Shias can be traced to Hakim ibn Jabalah al-Abdi, a companion of the Islamic Prophet Muhammad, who traveled across Sind to Makran in the year 649AD and presented a report on the area to the Caliph. He supported Ali, and died in the Battle of the Camel alongside Sindhi Jats.[136] He was also a poet and few couplets of his poem in praise of Ali ibn Abu Talib have survived, as reported in Chachnama:[137]

(Arabic:

ليس الرزيه بالدينار نفقدة

ان الرزيه فقد العلم والحكم

وأن أشرف من اودي الزمان به

أهل العفاف و أهل الجود والكريم [138]

‎ "Oh Ali, owing to your alliance (with the prophet) you are truly of high birth, and your example is great, and you are wise and excellent, and your advent has made your age an age of generosity and kindness and brotherly love".[139]

During the reign of Ali, many Jats came under the influence of Shi'ism.[140] Harith ibn Murrah Al-abdi and Sayfi ibn Fil' al-Shaybani, both officers of Ali's army, attacked Sindhi bandits and chased them to Al-Qiqan (present-day Quetta) in the year 658.[141] Sayfi was one of the seven Shias who were beheaded alongside Hujr ibn Adi al-Kindi[142] in 660AD, near Damascus.

Ali is said to have vowed an uncompromising campaign against financial corruption and unfair privileges after he assumed the caliphate following the death of Uthman. Shias argue that his determination in pushing these reforms aroused the ire of the wealthy and the privileged former companions of the Prophet.[143][144] In a well-known letter to one of his governors, Malik al-Ashtar, he articulates his pro-poor, anti-elitist approach:

Remember that displeasure and disapproval of common men, have-nots and depressed persons more than overbalances the approval of important persons and displeasure of a few big will be excused by the Lord if the general public and masses of your subjects are happy with you. The common men, the poor, apparently less important sections of your subjects are the pillars of Islam….be more friendly with them and secure their confidence and sympathy.[144]

'Ali recovered the land granted by 'Uthman and swore to recover anything that elites had acquired before his election. Ali opposed the centralisation of capital control over provincial revenues, favouring an equal distribution of taxes and booty amongst the Muslim citizens; he distributed the entire revenue of the treasury among them. 'Ali refrained from nepotism, including with his brother 'Aqeel ibn Abu Talib. This reflected his policy of offering equality to Muslims who served Islam in its early years and to those Muslims who played a role in the later conquests.[2][145]

Ali succeeded in forming a broad coalition, especially after the Battle of the Camel. His policy of equal distribution of taxes and booty gained the support of Muhammad's companions, especially the Ansar who were subordinated by the Quraysh leadership after Muhammad, the traditional tribal leaders, and the Qurra or Qur'anic reciters that sought pious Islamic leadership. The successful formation of this diverse coalition seems to be due to Ali's charisma.[2][146] This diverse coalition became known as Shia Ali, "adherents of Ali" or "followers of Ali". However, according to Shia, as well as non-Shia reports, the majority of those who supported 'Ali after his election as caliph were Shia politically, not religiously. Although at this time there were many who were counted as political Shia, few of them believed in Ali's religious leadership.[147]

His policies and ideas of governing are manifested in the letter he sent to Malik al-Ashtar after appointing him governor of Egypt. This instruction, which has historically been viewed as the ideal constitution for Islamic governance, alongside the Constitution of Medina, involved detailed descriptions of the duties and rights of the ruler, the various functionaries of the state, and the main classes of society at that time.[148][149] Ali wrote:

Infuse your heart with mercy, love and kindness for your subjects. Be not in face of them a voracious animal, counting them as easy prey, for they are of two kinds: either they are your brothers in faith or in creation. Error catches them unaware, deficiencies overcome them, (evil deeds) are committed by them intentionally and by mistake. So grant them your pardon and your forgiveness to the same extent that you hope God will grant you His pardon and His forgiveness. For you are above them, and he who appointed you is above you, and God is above him who appointed you. God has sought from you the fulfillment of their requirements and He is trying you with them.[150]

Since the majority of 'Ali's subjects were nomads and peasants, he was concerned with agriculture. He instructed Malik to give more attention to land development than to the tax collection, because tax can only be obtained by the development of the land and whoever demands tax without developing the land ruins the country and destroys the people.[151]

The Great Mosque of Kufa, where Ali was fatally attacked

On 19 Ramadan AH 40, which would correspond to 26 January 661,[152] while praying in the Great Mosque of Kufa, Ali was attacked by the Kharijite Abd-al-Rahman ibn Muljam. He was wounded by ibn Muljam's poison-coated sword while prostrating in the Fajr prayer.[153] 'Ali ordered his sons not to attack the Kharijites, instead stipulating that if he survived, ibn Muljam would be pardoned whereas if he died, ibn Muljam should be given only one equal hit (regardless of whether or not he died from the hit).[154] 'Ali died two days later on 29 January 661 (21 Ramadan AH 40).[2][153] Al-Hasan fulfilled Qisas and gave equal punishment to ibn Muljam upon Ali's death.[135]

According to Al-Shaykh Al-Mufid, Ali did not want his grave to be desecrated by his enemies and consequently asked his friends and family to bury him secretly. This secret gravesite was revealed later during the Abbasid caliphate by Imam Ja'far al-Sadiq, his descendant and the sixth Shia Imam.[158] Most Shias accept that Ali is buried at the Tomb of Imam Ali in the Imam Ali Mosque at what is now the city of Najaf, which grew around the mosque and shrine called Masjid Ali.[159][160]

However, another story, usually maintained by some Afghans, notes that his body was taken and buried in the Afghan city of Mazar-E-Sharif at the famous Blue Mosque or Rawze-e-Sharif.[161]

According to a hadith which is narrated by Shia and Sufis, Muhammad said "I'm the city of knowledge and Ali is its gate ..."[160][162][163] Muslims regard Ali as a major authority on Islam. According to the Shia, Ali himself gave this testimony:

Not a single verse of the Quran descended upon (was revealed to) the Messenger of God which he did not proceed to dictate to me and make me recite. I would write it with my own hand, and he would instruct me as to its tafsir (the literal explanation) and the ta'wil (the spiritual exegesis), the nasikh (the verse which abrogates) and the mansukh (the abrogated verse), the muhkam and the mutashabih (the fixed and the ambiguous), the particular and the general ...[164]

It has been narrated that when Abbas was a baby, Ali placed him on his lap, kissed his hands and began to weep. He foretold the tragedy of Abbas and the inevitable fate of his hands which caused his wife, Umm ul-Banin, to also weep. However, he goes on to describe Abbas's future position and great status with God, and this relieves her.[44]

According to Seyyed Hossein Nasr, Ali is credited with having established Islamic theology, and his quotations contain the first rational proofs among Muslims of the Unity of God.[165] Ibn Abi al-Hadid has quoted

As for theosophy and dealing with matters of divinity, it was not an Arab art. Nothing of the sort had been circulated among their distinguished figures or those of lower ranks. This art was the exclusive preserve of Greece, whose sages were its only expounders. The first one among Arabs to deal with it was Ali.[166]

In later Islamic philosophy, especially in the teachings of Mulla Sadra and his followers, like Allameh Tabatabaei, Ali's sayings and sermons were increasingly regarded as central sources of metaphysical knowledge, or divine philosophy. Members of Sadra's school regard Ali as the supreme metaphysician of Islam.[1] According to Henry Corbin, the Nahj al-Balagha may be regarded as one of the most important sources of doctrines professed by Shia thinkers, especially after 1500. Its influence can be sensed in the logical co-ordination of terms, the deduction of correct conclusions, and the creation of certain technical terms in Arabic which entered the literary and philosophical language independently of the translation into Arabic of Greek texts.[167]

In addition, some hidden or occult sciences such as jafr, Islamic numerology, and the science of the symbolic significance of the letters of the Arabic alphabet, are said to have been established by Ali[1] through his having studied the texts of al-Jafr and al-Jamia.

Ali was also a great scholar of Arabic literature and pioneered in the field of Arabic grammar and rhetoric. Numerous short sayings of Ali have become part of general Islamic culture and are quoted as aphorisms and proverbs in daily life. They have also become the basis of literary works or have been integrated into poetic verse in many languages. Already in the 8th century, literary authorities such as 'Abd al-Hamid ibn Yahya al-'Amiri pointed to the unparalleled eloquence of Ali's sermons and sayings, as did al-Jahiz in the following century.[1] Even staffs in the Divan of Umayyad recited Ali's sermons to improve their eloquence.[168] The most famous selection of Ali's utterances and writings has been gathered in a book called Nahj al-Balagha (Peak of Eloquence) by a 10th-century Shia scholar, Al-Sharif al-Radi, who selected them for their singular rhetorical beauty.[169]

Of note among sermons quoted in the book is the undotted sermon as well as the sermon without Aleph.[170] According to narrations, some companions of Muhammad had gathered somewhere discussing the role of letters in speaking. They concluded that Aleph had the greatest contribution in speaking and that dotted letters were also important. Meanwhile, Ali read two long impromptu sermons, one without using Aleph and the other without dotted letters, containing deep and eloquent concepts, according to Langroudi, a Shia author.[171] George Jordac, a Christian author, said that sermons without Aleph and dot had to be regarded as literary masterpieces.[172]

Ali is revered for the deep sympathy and support he showed for the poor and orphans, and the egalitarian policies he pursued during his caliphate with the aim of achieving social justice. He is quoted as saying:

If God grants wealth and prosperity to any person, he should show kindness to his deserving kith and kin, should provide for the poor, should come the assistance of those are oppressed with calamities, misfortunes and reverses, should help the poor and have-nots and should assist honest people to liquidate their loans...[144]

It is narrated in Kitab al-Kafi that Amir al-Mu'minin Ali ibn Abi Talib was presented with honey and figs from locations near Baghdad. Upon receiving the gifts, he ordered his officers to bring the orphans so that they could lick the honey from the containers while he distributed the rest himself among the people.[173]

One of the first copies of the Qur'an ever transcribed in the Islamic world by 'Ali ibn Abi Talib.

The sermons, lectures and quotations attributed to Ali are compiled in several books:

• Nahj al-Balagha (The Peak of Eloquence) contains eloquent sermons, letters and quotations attributed to Ali, compiled by ash-Sharif ar-Radi (d. 1015). Reza Shah Kazemi states: "Despite ongoing questions about the authenticity of the text, recent scholarship suggests that most of the material in it can in fact be attributed to Ali" and in support of this he makes reference to an article by Mokhtar Jebli.[160] This book has a prominent position in Arabic literature. It is also considered an important intellectual, political and religious work in Islam.[1][174][175] The Urdu translator of Nahjul Balagha Allama Syed Zeeshan Haider Jawadi[176] has compiled a list of 61 books and name of their writers from AH 204 to 488, and provided the sources in which compilation work of Sharif Razi can be traced out. Masadir Nahj al-Balagha wa asaniduh, written by al-Sayyid 'Abd al-Zahra' al-Husayni al-Khatib, introduces some of these sources.[177] Also, Nahj al-sa'adah fi mustadrak Nahj al-balaghah by Muhammad Baqir al-Mahmudi represents all of Ali's extant speeches, sermons, decrees, epistles, prayers, and sayings that have been collected. It includes the Nahj al-balagha and other discourses which were not incorporated by ash-Sharif ar-Radi or were not available to him. Apparently, except for some of the aphorisms, the original sources of all the contents of the Nahj al-balagha have been determined.[174] There are several Comments on the Peak of Eloquence by Sunnis and Shias such as Comments of Ibn Abi al-Hadid and comments of Muhammad Abduh.
• Supplications (Du'a), translated by William Chittick.[178]
• Ghurar al-Hikam wa Durar al-Kalim (Exalted aphorisms and Pearls of Speech) which is compiled by Abd al-Wahid Amidi (d. 1116) consists of over ten thousand short sayings of Ali.[179]
• Divan-i Ali ibn Abu Talib (poems which are attributed to Ali ibn Abu Talib).[2]

Ali had four children with Muhammad's youngest daughter Fatimah: Al-Hasan, Al-Husayn, Zaynab[1] and Umm Kulthum. After Fatimah's death, he married Umamah the daughter of Zaynab the elder daughter of Muhammad, and had two sons with her: Hilal (also known as "Muhammad al-Awsat or Muhammad the Middle"), and 'Awn.[11] His other well-known sons were Al-Abbas ibn Ali, born to Umm al-Banin Fatimah binte Hizam, and Muhammad ibn al-Hanafiyyah,[193] from Khawlah bint Ja'far, another wife from the central Arabian tribe of Banu Hanifah, whom Ali had also married after Fatimah's death.

Hasan, born in 625, was the second Shia Imam and he also assumed the role of caliph for several months after Ali's death. In the year AH 50 he died after being poisoned by a member of his own household who, according to historians, had been motivated by Mu'awiyah.[194] Husayn, born in 626, was the third Shia Imam, whom Mu'awiyah persecuted severely. On the tenth day of Muharram, of the year 680, Husayn lined up before the army of the caliph with his small band of followers and nearly all of them were killed in the Battle of Karbala. The anniversary of his death is called the Day of Ashura and it is a day of mourning and religious observance for Shia Muslims.[195] In this battle some of Ali's other sons were killed. Al-Tabari has mentioned their names in his history: Al-Abbas ibn Ali, the holder of Husayn's standard, Ja'far, Abdallah and Uthman, the four sons born to Fatima binte Hizam; Muhammad and Abu Bakr. There is, however, some doubt as to whether the last died in the battle.[196] Some historians have added the names of Ali's other sons who were killed at Karbala, including Ibrahim, Umar and Abdallah ibn Al-Asqar.[197][198] His daughter Zaynab—who was in Karbala—was captured by Yazid's army and later played a great role in revealing what happened to Husayn and his followers.[199] Ali's descendants by Fatimah are known as sharifs, sayeds or sayyids. These are honorific titles in Arabic, sharif meaning 'noble' and sayed or sayyid meaning 'lord' or 'sir'. As Muhammad's descendants, they are respected by both Sunnis and Shi'ites.[1]

Both of his sons by Umamah bint Zaynab, that is Hilal and 'Awn, died in Iran, with the latter having been martyred in a battle against Qays ibn Murrah (the governor of Khorasan), and the former dying naturally.[11]

Ali's descendants through his son Abbas are known as Awans or Alvis. Today, most of them reside in modern-day Pakistan. They are descendants of Qutb Shah who is a direct descendant of Ali, and his lineage is traced as Qutb Shah (Aawn) ibn Yaala ibn Hamza ibn Qasim ibn Tayyar ibn Qasim ibn Ali ibn Jaffar ibn Humza ibn al-Hassan ibn Ubaidullah ibn Abbas ibn Ali ibn Abu Talib.[200][201][202][203][204][205][206][207][208]

Except for Muhammad, there is no one in Islamic history about whom as much has been written in Islamic languages as Ali.[1] In Muslim culture, Ali is respected for his courage, knowledge, belief, honesty, unbending devotion to Islam, deep loyalty to Muhammad, equal treatment of all Muslims and generosity in forgiving his defeated enemies, and therefore is central to mystical traditions in Islam such as Sufism. Ali retains his stature as an authority on Quranic exegesis, Islamic jurisprudence and religious thought.[157] Ali holds a high position in almost all Sufi orders which trace their lineage through him to Muhammad. Ali's influence has been important throughout Islamic history.[1] Sunni and Shia scholars agree that The Verse of Wilayah was narrated in honour of Ali, but there are differing interpretations of wilayah and the Imamate.[209] The Sunni scholars believe that the verse is about Ali but does not recognise him as an Imam while, in the Shia Muslim view, Ali had been chosen by God as successor of Muhammad.[210]

There are many verses interpreted by Shia scholars as referring to Ali or other Shia Imams. In answering question of why the names of the Imams are not expressly mentioned in the Quran Muhammad al-Baqir responds:[lower-alpha 1] "Allah revealed Salat to his Prophet but never said of three or four Rakats, revealed Zakat but did not mention to its details, revealed Hajj but did not count its Tawaf and the Prophet interpreted their details. Allah revealed this verse and Prophet said this verse is about Ali, Hasan, Husayn and the other twelve Imams."[211][212] According to Ali, one quarter of Qur'anic verses are stating the station of Imams. Momen has listed many of these verses in his An Introduction to Shi'i Islam.[213][214] However, there are few verses that some Sunni commentators interpret as referring to Ali, among which are The verse of Wilayah (Quran, 5:55) that Sunni and Shia scholars[lower-alpha 2] believe refers to the incident where Ali gave his ring to a beggar who asked for alms while performing ritual prayers in the mosque.[209][215] The verse of Mawadda (Quran, 42:23) is another verse in which Shia scholars, along with Sunni ones like Al-Baydawi and Al-Zamakhshari and Fakhr ad-Din ar-Razi, believe that the phrase Kinship refers to Ali, Fatimah and their sons, Hasan and Husayn.[216][217][218][219]

The verse of purification (Quran, 33:33) is also among the verses in which both Sunnis and Shia conjoined the name of Ali along with some other names.[lower-alpha 3][213][217][220][221][222][223] The aforementioned verse of Mubahala, and also Quran 2:269, in which Ali is honoured with unique wisdom by both Shia and Sunni commentators, are other verses of this kind.[213][217][224]

The Shia regard Ali as the most important figure after Muhammad[225] and he represents a complex, legendary figure in their memory. He is a paragon of virtues, such as courage, magnanimity, sincerity, straightforwardness, eloquence and profound knowledge. Ali was righteous but suffered injustice, he was authoritative but also compassionate and humble, vigorous but also patient, learned but also a man of labor.[226] According to Shia, Muhammad suggested on various occasions during his lifetime that Ali should be the leader of Muslims after his death. This is supported by numerous hadiths which have been narrated by Shias, including Hadith of the pond of Khumm, Hadith of the two weighty things, Hadith of the pen and paper, Hadith of the Cloak, Hadith of position, Hadith of the invitation of the close families, and Hadith of the Twelve Successors.

Ja'far al-Sadiq narrates in hadith that whatever virtue found in Muhammad was found in Ali, and that turning away from his guidance would be akin to turning away from Allah and his Prophet. Ali himself narrates that he is the gateway and supervisor to reach Allah.[173]

According to this view, Ali as the successor of Muhammad not only ruled over the community in justice, but also interpreted the Sharia Law and its esoteric meaning. Hence he was regarded as being free from error and sin (infallible), and appointed by God by divine decree (nass) through Muhammad. It is believed in Twelver and Ismaili Shaa Islam that 'aql, divine wisdom, was the source of the souls of the Prophets and Imams and gave them esoteric knowledge called ḥikmah and that their sufferings were a means of divine grace to their devotees.[1][227] Although the Imam was not the recipient of a divine revelation, he had a close relationship with God, through which God guides him, and the Imam in turn guides the people. His words and deeds are a guide and model for the community to follow; as a result it is a source of sharia law.[228][229]

Shia pilgrims usually go to Mashad Ali in Najaf for Ziyarat, pray there and read "Ziyarat Amin Allah"[230] or other Ziyaratnamehs.[231] Under the Safavid Empire, his grave became the focus of much devoted attention, exemplified in the pilgrimage made by Shah Ismail I to Najaf and Karbala.[33]

Sunnis view Ali as the fourth caliph. Ali is also known as one of the greatest warrior champions of Islam. Examples include taking on the Quraish champion at the Battle of the Trench when nobody else dared. After multiple failed attempts to break the fort in the Battle of Khaybar, Ali was summoned, miraculously healed, and he captured the fort.[232]

Muhammad ibn Idris Al-Shafi‘i, founder of the Shafi‘i school of fiqh, stated the following when asked his opinion on Ali:

"What can we say about a person whose partisans have had to hide his merits because of fear, and enemies have hidden his merits out of envy? Nevertheless between these two, his merits that have become widely known are too numerous to be counted."[44]^:6

Almost all Sufi orders trace their lineage to Muhammad through Ali,an exception being Naqshbandi, who go through Abu Bakr. Even in this order, there is Ja'far al-Sadiq, the great great grandson of Ali. Sufis believe that Ali inherited from Muhammad the saintly power wilayah that makes the spiritual journey to God possible.[1]

Early sufi Hasan Al Basri was disciple of Ali.Eminent Sufis such as Ali Hujwiri claim that the tradition began with Ali and Junayd of Baghdad regarded Ali as the Sheikh of the principles and practices of Sufism.[233]

Sufis recite Manqabat Ali in the praise of Ali.

Ali is known by various titles, some given due to his personal qualities and others due to events in his life:[1]

• Al-Murtaza (Arabic: ٱلْمُرْتَضَىٰ‎, "The Chosen One")
• Amir al-Mu'minin (Arabic: أَمِير ٱلْمُؤْمِنِين‎, "Commander of the Faithful Ones")
• Bab-e Madinatul-'Ilm (Arabic: بَابِ مَديْنَةُ ٱلْعِلْم‎, "Door of City of the Knowledge")
• Abu Turab (Arabic: أَبُو تُرَاب‎, "Father of the Soil")
• Asad Allah (Arabic: أَسَد ٱلله‎, "Lion of God")
• Haydar (Arabic: حَيْدَر‎, "Braveheart" or "Lion")
• Walad al-Kaʿbah (Arabic: وَلَد ٱلْکَعْبَة‎, "Son of the Kaaba")[234]

Ali is recorded in some traditions as having forbidden those who sought to worship him in his own lifetime.[235]

Some groups such as the Alawites are claimed to believe that Ali was God incarnate. They are described as ghulat (Arabic: غُلَاة‎, "exaggerators") by the majority of Islamic scholars. These groups have, according to traditionalist Muslims, left Islam due to their exaggeration of a human being's praiseworthy traits.[235] Studies carried out by Aryeh Kofsky and Meir M.Bar Asher support the claim that the Alawites do not deify Ali but rather identify him as the unique "wasīī", meaning a "guard of Islam" chosen by God [236]

Ali-Illahism, a syncretic religion, centres on the belief that there have been successive incarnations of their Deity throughout history, and reserves particular reverence for 'Ali, the son-in-law of Muhammad, who is considered one such incarnation.[237]

The Druze faith, a syncretic religion, holds that God was incarnated in human beings, especially Al-Hakim bi-Amr Allah a descendant of Ali.
