Sirāj al-Dīn ʿUmar b. ʿAbd al-ʿAzīz

Sirāj al-Dīn ʿUmar b. ʿAbd al-ʿAzīz was a Kharubbi merchant and a member of the Karimi merchant guild that traded spices, perfumes, sugar, pottery, textiles, and other goods between the Indian Ocean and the Mediterranean Sea during the Ayyubid and Mamluk periods.

He inherited his uncle's property and further expanded his business.

He married the daughter of another prominent and wealthy merchant, Nasir al-Din Muhammad Ibn Musallam (died 1374) in order to form ties between two families and improve his business connections.

Unfortunately, over the time, he devoted himself to Sufism and other religious activities neglecting the family business and running up debts. Allegedly, he wanted nothing more than to hear the Qur'an recited, and died heavily in debt.
