Abū Jaʿfar Muḥammad ibn ʿAlī al-Hādī (Arabic: أبو جعفر محمد بن علي الهادي) was a descendant of the Islamic prophet Muhammad and the son of Ali al-Hadi (d. 868) and the brother of Hasan al-Askari (d. 874), the tenth and eleventh Imams in Twelver Shia, respectively. Some may have expected him to succeed his father al-Hadi to the imamate but he predeceased him in the garrison town of Samarra in Iraq, where al-Hadi was kept under surveillance by the Abbasids. His shrine is located near Baghdad, between Samarra and Kadhimiya. Considered a sacred site in Twelver Shia, his shrine was targeted by Sunni militants in 2016 in a deadly attack on its pilgrims.
