Death of al-Mahdi

In 169 AH, eight nights before the end of Muharram, al-Mahdi died. He rode in pursuit of game, the game ran into a ruin and he followed it, and his back struck the doorway, and he died instantly. It is also said that he died poisoned. ¹

The second account, the poison account, is related by al-Suyuti with the phrase "it is said". The report comes from a single source and needs an additional source.
