Mus'ab ibn Umayr

Mus'ab ibn Umayr was one of the earliest Companions (sahaba) of the Prophet Muhammad. He belonged to the Banu Abd al-Dar, a clan of the Quraysh tribe that dominated Mecca, and the sira (traditional biographical literature) remembers him as a wealthy, finely dressed young man before his conversion. He is reported to have embraced Islam around 614 CE after hearing the Qur'an recited at the house of al-Arqam, an early gathering-place for Muslims. Tradition holds that his mother, Khunas bint Malik, confined him to force him to recant; the precise details are preserved in sira accounts rather than independently documented.

His signature role in the tradition comes after the First Pledge of Aqaba (traditionally c. 621 CE), when a delegation from Yathrib (later Medina) accepted Islam. Sources report that the Prophet sent Mus'ab to Yathrib as a teacher and reciter (qari) of the Qur'an, where he was hosted by As'ad ibn Zurarah of the Khazraj; in the standard telling he is remembered as the first emissary of Islam sent to that city, credited with the conversion of leading men of the Aws and Khazraj, including Sa'd ibn Mu'adh and Usayd ibn Hudayr.

He is reported to have fought at Badr (2 AH) and carried the Muslim standard at the Battle of Uhud (3 AH / 625 CE), where he was killed (sira names his slayer as Ibn Qami'a). His death at Uhud is the firmly attested anchor of his biography; the moving deathbed details (his hands severed while holding the banner, his shroud too short to cover his body) come from hadith and sira and are traditionally held rather than externally verified.
