Abu Ishaq Ibrahim ibn Muḥammad ibn ʿAlī ibn ʿAbd Allāh ibn al-ʿAbbās (701/2 CE–749), better known as Ibrahim al-Imam (إبراهيم الإمام), was the leader of the Abbasid family and of the clandestine Hashimiyya movement that prepared and launched the Abbasid Revolution against the Umayyad Caliphate.
He inherited the leadership of the movement from his father, Muhammad, in 743, and played a major role in its spread in Khurasan, not least by appointing Abu Muslim as the local leader. Ibrahim did not live to see the success of the revolution, being imprisoned and dying in August 749, either killed at the orders of the last Umayyad caliph, Marwan II, or from the plague. Shortly after, his brother Abu al-Abbas became the first Abbasid caliph with the name al-Saffah.
