The Alid revolt of 762–763 or Revolt of Muhammad the Pure Soul was an uprising by the Hasanid branch of the Alids against the newly established Abbasid Caliphate. The Hasanids, led by the brothers Muhammad (called "the Pure Soul") and Ibrahim, rejected the legitimacy of the Abbasid family's claim to power. Reacting to mounting persecution by the Abbasid regime, in 762 they launched a rebellion, with Muhammad rising in revolt at Medina in September and Ibrahim following in Basra in November.
The Hasanid's lack of co-ordination and organization, as well as the lukewarm support of their followers, allowed the Abbasids under Caliph al-Mansur to react swiftly. The Caliph contained Muhammad's rebellion in the Hejaz and crushed it only two weeks after Ibrahim's uprising, before turning his forces against the latter. Ibrahim's rebellion had achieved some initial successes in southern Iraq, but his camp was torn by dissent among rival Shi'a groups as to the prosecution of the war and future political objectives.
