Sa'id was a son of Caliph
Uthman () and the latter's wife Fatima bint al-Walid, a scion of the prominent
Banu Makhzum clan of the
Quraysh. Caliph
Mu'awiya I () had partly based his claim to the caliphate on his pursuit of justice for the assassination in 656 of Uthman, his
Umayyad kinsman. Upon hearing news that he had nominated his son
Yazid I () as his successor, Sa'id left Medina for Mu'awiya's court in Damascus to petition against the decision. According to the accounts of the medieval Muslim historians
al-Mada'ini (d. 843) and
al-Baladhuri (d. 892), Sa'id visited Damascus to demand a high-ranking office from Mu'awiya and that the latter questioned Sa'id about rumors that he was seeking the caliphate. Sa'id, in turn, argued that because he was a son of Uthman and that his mother was a noble Qurayshite (as opposed to Yazid whose mother
Maysun bint Bahdal was a
Kalbite tribeswoman), he was indeed a more legitimate candidate for the caliphate than Yazid. Sa'id had been supported or encouraged to claim the office by people in Medina, including a segment of the elite
Ansar faction. He may have also been quietly encouraged by
Marwan ibn al-Hakam, a senior Umayyad in Medina who resented Mu'awiya's rule and sought to restore the office to the Abu al-As branch of the Umayyad clan, to which Marwan and Sa'id belonged (Mu'awiya belonged to the Sufyanid branch). Mu'awiya accepted the merit of Sa'id's arguments, though
Ibn Kathir (d. 1373) holds that the caliph rejected Sa'id's assertion that he was more worthy than Yazid.
Governorship of Khurasan Depending on the source, during his meeting with Sa'id, Mu'awiya recommended that he should take up office in
Khurasan, the easternmost province of the
Caliphate, or granted this to Sa'id per the latter's own request. In any event, the caliph sent Sa'id to
Ubayd Allah ibn Ziyad, the governor of
Basra and the eastern Caliphate, with directions to assign Sa'id commander of the conquests in Khurasan in 675/76. Per the caliph's instructions, Ibn Ziyad allotted Sa'id four million
dirhams to distribute among the 4,000 soldiers under his command. Though there were capable commanders among the men assigned to Sa'id, including
al-Muhallab ibn Abi Sufra, many of the troops collected were Basran prisoners and otherwise disruptive tribal elements from the population. On the way to Khurasan, Sa'id further recruited highwaymen from the
Banu Tamim to join his ranks. Mu'awiya restricted Sa'id's jurisdiction to military affairs, assigning fiscal responsibilities to
Ishaq ibn Talha, who died en route to Khurasan and was replaced in the role by
Aslam ibn Zur'a al-Kilabi, a
Qaysite tribal leader in the Khurasan garrison and the province's former lieutenant governor. According to the historian Muhammad Shaban, Mu'awiya's deployment of Sa'id and Ishaq represented efforts to ensure that the surplus tax revenue of Khurasan, in addition to the traditional fifth of the war booty from the conquests there, was forwarded to the caliphal treasury in Damascus. This was generally opposed by the Arab tribesmen who made up the ranks of Khurasan's garrisons, who sought to keep the bulk of the provincial revenue under their control. With Ishaq's death and Aslam's virtual usurpation of the former's role, as well as Mu'awiya's efforts to keep good relations with the Qaysites so that their Syrian counterparts would accept Yazid's nomination, Sa'id was forced to work with Aslam as his partner-in-government. After preparing his army, Sa'id launched a campaign east of the
Oxus river, deeper than the previous campaign of 674 by Ibn Ziyad, and defeated a
Soghdian army on the open field before capturing one of their cities and then occupying the
Tirmidh fortress. The traditional Muslim histories of
Abu Ubayda (d. 825), al-Baladhuri,
al-Tabari (d. 923),
Narshakhi (d. 959) offer varying accounts of the campaign. Al-Baladhuri and Narshakhi hold that Sa'id's crossing of the Oxus prompted Khatun, the queen of
Bukhara to give allegiance to the Caliphate, but she then reneged upon the arrival of a supportive 120,000-strong army of Turks, Soghdians and soldiers from
Kish and
Nasaf. Sa'id's forces decisively defeated this army, entered Bukhara in triumph and, boosted by numerous defectors among the Soghdian army, besieged
Samarkand for three days, after which it became a tributary of the Caliphate. Abu Ubayda also records that Sa'id besieged Samarkand. He then proceeded to capture Tirmidh and it was there that he received the tribute owed by Khatun and the allegiance of
Principality of Khuttal.
Dismissal, death and legacy Mu'awiya relieved Sa'id of his post in 677. This may have stemmed from Sa'id's growing popularity and battlefield successes, which could potentially reinforce his claims as a legitimate rival to Yazid.
Ibn Asakir (d. 1176) relates that Sa'id had returned to Medina after Mu'awiya's death in 680. On his return, he took with him fifty Soghdian nobles as slaves whom he employed to work his land. He abused them by confiscating their valuables and having them dressed in wool. A number of the Soghdians then killed Sa'id, possibly with their shovels, in his walled garden before killing themselves. Marwan had attempted to rescue Sa'id, but was unable as the Soghdians had locked the garden's gate. Sa'id had at least two wives, one of whom was Ramla (not
Umm Habiba), the daughter of Mu'awiya's father and a leading figure among the Quraysh,
Abu Sufyan ibn Harb; the other wife is not named in the sources. From Ramla, Sa'id had his son Muhammad, about whom nothing is known in the sources, and A'isha, who married Abd Allah, the son of Mu'awiya I. From his second wife, Sa'id had a daughter called Umm Sa'id who successively married Caliph
Hisham ibn Abd al-Malik (),
al-Abbas ibn al-Walid (son of Caliph
al-Walid I, ) and
Abd al-Aziz ibn Umar (son of Caliph
Umar II, ). Another son of Sa'id recorded in the sources was Aban, whose
mawla (non-Arab, Muslim freedman) was a high-ranking supporter of the Umayyad rebel
Abu al-Umaytir in his early 9th-century revolt against the
Abbasids, who had overthrown the Umayyads in 750. ==References==
