Abdallah rose in revolt in 746, rapidly seizing control of the Hadramawt and Yemen.[2][4] In mid-747, at the time of the Hajj pilgrimage, Abdallah entrusted al-Mukhtar with some 900–1,000 strong, and sent him to occupy the two Islamic holy cities of Mecca and Medina.[2][4] Al-Mukhtar seized Mecca in August 747 without a fight,[5] but before Medina was opposed by a local force, which he defeated with great loss of life in October 747.[6]
The expansion of the Ibadi uprising worried the Umayyad caliph Marwan II, who in January 748 Marwan sent his general, Abd al-Malik ibn Atiyya, to suppress it with 4,000 troops. The Umayyad general defeated and killed Abu Hamza before Medina and retook control of the Hejaz.[2][7][8]
