Abd Allah ibn Abi Sarh

Abd Allah ibn Abi Sarh al-Amiri (died ca. 36–37 AH) was a Companion with one of the most complicated histories in early Islam. He was a member of the Umayyad clan and a foster brother of Uthman ibn Affan. He accepted Islam early in Mecca and served as one of the scribes of Quranic revelation — a position of enormous trust and proximity to the Prophet ﷺ.

He later apostatized, fled to Mecca, and was among those the Prophet ﷺ declared exempt from the general pardon at the conquest of Mecca — meaning he was to be killed even if found under the covering of the Ka'bah. His apostasy and the reasons behind it are discussed in the early sources, with accounts suggesting he made alterations while scribing and then claimed the Prophet approved them. Uthman ibn Affan, his foster brother, interceded for him at the conquest of Mecca, and after some hesitation the Prophet ﷺ granted him clemency.

After the conquest, Abd Allah ibn Abi Sarh accepted Islam again, embraced it fully, and went on to serve the Muslim state with distinction. He became a capable military commander and was appointed governor of Upper Egypt under Uthman ibn Affan. In this capacity he conducted highly successful naval operations against the Byzantines, winning the Battle of the Masts (Dhat al-Sawari) in 34 AH — one of the first major Muslim naval victories and a decisive engagement in the western Mediterranean.

He died during the First Fitna, around 36–37 AH, either in combat or in retirement. His life encapsulates the complexity of conversion, apostasy, redemption, and service that characterized the tumultuous first generation of Islam.
