(d. ca. 652)
Companion of Muhammad. Among the first converts to Islam. Held administrative and diplomatic duties under the caliphs Umar and Uthman, but eventually broke with the latter. One of the most prolific transmitters of hadith, especially via the transmitters of Kufa, where he settled. He is especially important for traditions on the interpretation of the Quran, having been present for many revelations. The Quranic reading differing from the official Uthmanic text, notably in omitting verses 1:113–14, is attributed to him. His career and reputation were marked by his humble Bedouin origins, personal loyalty to the Prophet, and subsequent conflict with the Meccan aristocracy.
