Editing Abu Mohammad Hasan ibn ali (section)

==Imamat==
He and his father, [[Ali AL-Hadi|Ali al-Hadi]], were taken by the caliph al-Motawakkel to Askar Samarra. According to Imamite tradition, his father designated Hasan al-Askari as his successor a few months before his death in 254/868<ref>Shaikh Mofid, Ersad, p. 335</ref>;  his elder brother, Abu Jaʿfar Moḥammad, was already dead by this time<ref>Nawbakti, p. 78</ref>.  It seems, however, that his right to the succession was challenged by his brother Jaʿfar.
