It is narrated from Ibn Shihab that (his lineage is) Uthman bin Affan bin Abi al-As bin Umayyah bin Abd Shams bin Abd Manaf bin Qusayy bin Kilab. The mother of Uthman (may Allah be pleased with him) was Arwa bint Kurayz, and the mother of Arwa was Umm Hakim, who was called "al-Bayda'", and she was the paternal aunt of the Messenger of Allah (peace and blessings be upon him). There is a difference of opinion about the kunyah of Uthman (may Allah be pleased with him): some said "Abu Abdullah" and some said "Abu Amr".
