Al-Husayn Husam al-Din

He succeeded his brother al-Hasan Badr al-Din II in 1512, and held the post until his death in 1527, when he was succeeded by his son Ali Shams al-Din III.[1][2]

Towards the end of his life Moulana's health became poor and all of the affairs of D`awat were entrusted to Syedi Hasan bin Nuh. Any correspondence received from Hind, Sind or Yemen was referred to Syedi Hasan bin Nuh and he would attend to it. Syedi Hasan bin Nuh was a native of Bharuch, a town in Gujarat, India. He was a prominent trader, distinguished scholar and had trade relations in Yemen and other Arab lands. He settled in Yemen in 1498 and became student of previous dai, al-Hasan Badr al-Din II. He wrote 'Kitaab ul-Azhaar'.

Syedna Husain resided in Shibam Hadramawt and is buried in Masaar, Yemen.
