'the Attainer of God´s pleasure'),[1] died 825 or after 837, was a ninth century Alid leader who led a rebellion against the Abbasid Caliphate in the Yemen in the aftermath of the Fourth Fitna.
[3] Ibrahim became active as a rebel following the damaging civil war of 811–813 between the rival caliphs al-Amin and al-Ma'mun, which had greatly weakened the ability of the Abbasid government to maintain its authority in Baghdad and the provinces of the empire.
His severe administration of the province, which was characterized by frequent killings, acts of enslavement, and confiscations of private property, soon caused him to develop a reputation for brutality, and he became known by the title of al-Jazzar ("the Butcher").
[6] After spending several months in the Yemen, Ibrahim attempted to assert his authority over Mecca as well, and dispatched an army to the city to lead the pilgrimage of 816 in the name of the Alids.
Upon their arrival at Mecca, however, his forces were unable to enter the city due to the presence of Abbasid reinforcements, and instead took to conducting raiding activities in the neighboring area until they were defeated and dispersed.
[7] Ibrahim's movements in the aftermath of his defeat against Hamdawayh are reported differently by various sources; al-Yaq'ubi states that he went straight to Mecca, while Yemeni writers claim that he remained in the province until 818, during which period he undertook punitive actions against a number of tribes that opposed him.
In response to his approach, the officer in command of the city, Yazid ibn Muhammad al-Makhzumi, came out to face him, but the rebels defeated him in battle, killing him and routing his forces.
