Abu Sa'id Aban ibn Uthman ibn Affan al-Umawi(Arabic:أَبُو سَعِيد أَبَان بْنُ عُثْمَانُ بْنُ عَفَّان الأُمَوِيّ,romanized: Abū Saʿīd Abān ibn ʿUthmān ibn ʿAffān al-Umawī; died 105 AH/723 CE) was a Muslim historian and traditionalist. He also served a seven-year stint as governor of Medina in 695–702, during the reign of theUmayyad caliphAbd al-Malik (r. 685–705).

Aban was a son ofUthman (r. 644–656), the thirdRashiduncaliph.^[1][2] His mother was Umm Amr bint Jundab ibn Amr al-Dawsiyya of theAzd tribe of Yemen.^[1][3][4] During theFirst Fitna, which occurred in the wake of his father's assassination, Aban fought alongside the forces of A'isha and hisUmayyad kinsmen against the fourth Rashidun caliphAli (r. 656–661) at theBattle of the Camel in November 656.^[3] As A'isha's supporters were on the verge of defeat, Aban fled the battle.^[1] Later, theUmayyad caliphAbd al-Malik (r. 685–705) appointed Aban governor ofMedina in 695 and he continued in the post until being replaced byHisham ibn Isma'il al-Makhzumi in 702.^[5] During his term, he led the funeral prayers, as was customary of the governor, forMuhammad ibn al-Hanafiyya, a son of Ali and leader of theAlid family.^[3]

He became incapacitated in 722/23 and died in Medina the following year, in 723/24, during the reign of CaliphYazid II.^[6] Aban does not appear to have been a major political operative of the Umayyads and owes most of his fame for his knowledge of Islamic tradition.^[7] He is credited by a number of scholars for authoring themaghazi (biography) ofMuhammad, though the historiansYaqut al-Hamawi andAhmad al-Tusi credit this work to a certain Aban ibn Uthman ibn Yahya.^[6]

Aban had at least two wives.^[3] His first, Umm Sa'id bint Abd al-Rahman, a granddaughter ofal-Harith ibn Hisham, belonged to theBanu Makhzum clan.^[3] She mothered two of Aban's sons, his eldest Sa'id and Abd al-Rahman, and a daughter.^[3] His second wife, Umm Kulthum bint Abd Allah was a granddaughter ofJa'far ibn Abi Talib.^[8] The names of the descendants of Aban have been recorded in the historical record up to at least 1375 in Egypt, where some of his descendants moved.^[8] Others are recorded in the sources inal-Andalus,^[9] including his grandson Uthman ibn Marwan and the latter's great-grandson Muhammad ibn Abd al-Rahman ibn Ahmad.^[10]
