The sons of Hisham ibn Isma'il al-Makhzumi, Ibrahim and Muhammad were maternal uncles of the caliph Hisham ibn Abd al-Malik (r. 724–743), who relied on them to act as his governors of the Hijaz for the majority of his reign.[1] Although the sources frequently confuse the two brothers,[2] Ibrahim appears to have been appointed as governor of Medina, Mecca and al-Ta'if in 724 and to have been dismissed in 732,[3] and was also the caliph's choice to lead the pilgrimages of 724, 726–731 and possibly 732.[4] During his governorship his appointees to lead the Medinese judiciary were Muhammad ibn Safwan al-Jumahi and al-Salt ibn Zubayd al-Kindi.[5]
In the last years of Hisham's reign Ibrahim and Muhammad were supporters of the caliph's unsuccessful plan to replace the heir-apparent al-Walid ibn Yazid with his own son Maslamah, but with the death of Hisham in 743 their political influence came to an end. Upon his accession to the caliphate al-Walid handed over the two brothers to his new governor of Medina, Yusuf ibn Muhammad ibn Yusuf al-Thaqafi, who paraded them in front of the city inhabitants and had them flogged; shortly afterwards al-Walid ordered Yusuf to transfer Ibrahim and Muhammad to Yusuf ibn Umar al-Thaqafi in Iraq, where together with Khalid ibn Abdallah al-Qasri they were tortured to death.[6] The brutal treatment of Ibrahim and Muhammad exacerbated hostility against al-Walid, playing a role in the caliph's own downfall and death and the outbreak of civil war in the following year.[7]
^Khalifah ibn Khayyat 1985, p. 357 states that Muhammad ibn Hisham was the governor of Mecca, Medina and al-Ta'if from 724 to 732 instead of Ibrahim, while Yarshater 1985–2007, v. 26: p. 8 and Al-Ya'qubi 1883, p. 397 claim that Ibrahim was governor in 739 and 743 respectively instead of Muhammad.
