A portion of the original inhabitants of the area that is now Saudi were nomads known as Bedouin. They remain a significant and very influential minority of the indigenous Saudi population, though many who call themselves "bedou" no longer engage in "traditional tribal activities of herding sheep and riding camels."[13] According to authors Harvey Tripp and Peter North, Bedouin make up most of the judiciary, religious leaders and National Guard (which protects the throne) of the country. Bedouin culture is "actively" preserved by the government.[13]

Some of the famous cities in the past were: Jeddah, Tabuk, Al-Ula, Jubbah, Madain Saleh, Riyadh, Tayma, Dumat al-Jandal, Al-Shuwayhatiyah, Thaj, Tarout Island, Qaryat al-Faw, Al-Ukhdud, Ha'il, Qatif, Al-Yamamah, Mecca, Medina, Taif, Aflaj, Manfouha, Tirmidah, etc.

Greetings in Saudi Arabia have been called "formal and proscribed" and lengthy. Saudis (men) tend "to take their time and converse for a bit when meeting". Inquiries "about health and family" are customary, but never about a man's wife, as this "is considered disrespectful."[14][15]

The religion and customs of Saudi Arabia dictate not only conservative dress for men and women, but a uniformity of dress unique to most of the Middle East.[16] Traditionally, the different regions of Saudi have had different dress, but since the re-establishment of Saudi rule these have been reserved for festive occasions, and "altered if not entirely displaced" by the dress of the homeland of their rulers (i.e. Najd). [17]

All women are required to wear an abaya a long cloak that covers all, but the hands, hair, and face in public. (Modest dress is compulsory for women in Islam but the color black for women and white for men is apparently based on tradition not religious scripture.[18]) Saudi women also normally wear a full face veil, such as a niqāb. Women's clothes are often decorated with tribal motifs, coins, sequins, metallic thread, and appliques. Foreign women are required to wear an abaya, but don't need to cover their hair.

In recent years it is common to wear Western dress underneath the abaya. (Foreign women in Saudi Arabia are "encouraged" by the religious police to wear an abaya, or at least cover their hair according to the New York Times.[19] Authors Harvey Tripp and Peter North encourage women to wear an abaya in "more conservative" areas of the kingdom, i.e. in the interior.[20])

Saudi men and boys, whatever their job or social status, wear the traditional dress called a thobe or thawb, which has been called the "Arabic dress".[21] During warm and hot weather, Saudi men and boys wear white thobes. During the cool weather, wool thobes in dark colors are not uncommon. At special times, men often wear a bisht or mishlah over the thobe. These are long white, brown or black cloaks trimmed in gold. A man's headdress consists of three things: the tagia, a small white cap that keeps the gutra from slipping off the head; the gutra itself, which is a large square of cloth; and the igal, a doubled black cord that holds the gutra in place. Not wearing an igal is considered a sign of piety. The gutra is usually made of cotton and traditionally is either all white or a red and white checked. The gutra is worn folded into a triangle and centred on the head.

• Ghutrah (Arabic: غترة‎ pronounced [ɣʊtra]) is a traditional keffiyeh headdress worn by men in the Arabian peninsula. It is made of a square of usually finer cotton cloth ("scarf"), folded and wrapped in various styles (usually a triangle) around the head. It is commonly worn in areas with an arid climate, to provide protection from direct sun exposure, and also protection of the mouth and eyes from blown dust and sand.
• Agal (Arabic: عقال‎ pronounced [ʕɪɡaːl]) is an item of Arab headgear constructed of cord which is fastened around the keffiyeh to hold it in place. The agal is usually black in colour.
• Abaya (Arabic: عباية‎ pronounced [ʕabaːja]) is a women's hijab worn by women when leaving the house. It is a black cloak that covers the entire body except for the head, although some abayas also cover the top of the head.
• Imama (Arabic: عمامة‎ pronounced [ʕɪmaːma]) is a type of the turban headdress native to the region of Hejaz in modern-day western Saudi Arabia, it is but one version of Arabian turbans that have been worn in the Arabian Peninsula from the pre-Islamic era to the present day. but in general nowadays most Hejazis wear Shumagh (Arabic: شُماغ‎ pronounced [ʃʊmaːɣ]) instead.
• Thawb (Arabic: ثوب‎ pronounced [θo̞ːb, t-]) is the standard Arabic word for garment. It is ankle length, woven from wool or cotton, usually with long sleeves similar to a robe.
• Bisht (Arabic: بشت‎ pronounced [bɪʃt]) is a traditional long, white, brown or black Arabic cloak trimmed in gold worn by men. It is usually only worn for prestige on special occasions such as weddings, or in chilly weather.

More recently, Western dress, particularly T-shirts and jeans have become quite common leisure wear, particularly in Jeddah, Riyadh and Eastern Province.[22] Traditional footwear has been leather sandals but most footwear is now imported.[17]

The official form of Islam is Sunni of the Hanbali school, in its Salafi version. According to official statistics, 85-90% of Saudi citizens are Sunni Muslims, 10-15% are Shia.[27] (More than 30% of the population is made up of foreign workers[27] who are predominantly but not entirely Muslim.) It is unknown how many Ahmadi there are in the country.[28] The two holiest cities of Islam, Mecca and Medina, are in Saudi Arabia. For many reasons, non-Muslims are not permitted to enter the holy cities although some Western non-Muslims have been able to enter, disguised as Muslims.[29][30]

The large number of foreign workers living in Saudi Arabia (7.5 million expatriates in 2013 A.D.[31]) includes non-Muslims. Irreligious population also exists in Saudi Arabia. Although there is no official published statistics by the Saudi government, according to a Gallup poll, 5% of Saudi Arabians are irreligious.[32][33][34] They may not enter Mecca either.

According to scholar Bernard Lewis, the Saudi Arabian policy of excluding non-Muslims from permanent residence in the country is a continuation of an old and widely accepted Muslim policy.

The classical Arabic historians tell us that in the year 20 after the hijra (Muhammad's move from Mecca to Medina), corresponding to 641 of the Christian calendar, the Caliph Umar decreed that Jews and Christians should be removed from Arabia to fulfill an injunction the Prophet uttered on his deathbed: "Let there not be two religions in Arabia." The people in question were the Jews of the oasis of Khaybar in the north and the Christians of Najran in the south.

[The hadith] was generally accepted as authentic, and Umar put it into effect. ... Compared with European expulsions, Umar's decree was both limited and compassionate. It did not include southern and southeastern Arabia, which were not seen as part of Islam's holy land. ... the Jews and Christians of Arabia were resettled on lands assigned to them -- the Jews in Syria, the Christians in Iraq. The process was also gradual rather than sudden, and there are reports of Jews and Christians remaining in Khaybar and Najran for some time after Umar's edict.

But the decree was final and irreversible, and from then until now the holy land of the Hijaz has been forbidden territory for non-Muslims. According to the Hanbali school of Islamic jurisprudence, accepted by both the Saudis and the declaration's signatories, for a non-Muslim even to set foot on the sacred soil is a major offense. In the rest of the kingdom, non-Muslims, while admitted as temporary visitors, were not permitted to establish residence or practice their religion.[35]

While Saudi Arabia does allow non-Muslims to live in Saudi Arabia to work or do business, they may not practice religion publicly. According to the government of the United Kingdom:

The public practice of any form of religion other than Islam is illegal; as is an intention to convert others. However, the Saudi authorities accept the private practice of religions other than Islam, and you can bring a Bible into the country as long as it is for your personal use. Importing larger quantities than this can carry severe penalties.[36]

Saudi Arabia still gives citizenship to people from other countries.[37]
