Editing Ali AL-Hadi (section)

==Martyrdom ==
According to Shi’ite accounts, he was poisoned through intrigue of Al-Mu'tazz the Abbasid caliph. According to Tabari and Kolayni, he died on 26 Jomada II 254/21 June 868. Other dates mentioned in the sources fall within Jomada II and Rajab 254/June-July, 868. The caliph Moʿtazz sent his brother Abu Ahmad Mowaffaq to lead the funeral prayer for him. When large crowds gathered to lament him, his corpse was returned to his house, which he had bought from the Christian Dolayl b. Yaʿqub, and was buried there. His son Abu Jaʿfar Muhammad, who had originally been expected to succeed him in the imamate, had died before him in Samarra. Two other sons survived him—Hasan, who became his successor, and Jaʿfar.
