H 309 - Ibn Abi Jayyid has narrated from Muhammad bin Hasan bin Walid from Saffar from Muhammad bin Isa that he said: Imam Hadi wrote to the Shia of Baghdad, Madayan, Sawad and the surrounding areas: I have appointed Abu Ali bin Rashid as successor to Husain bin Abde Rabb and the representatives before him; and their obedience is my obedience. I have written this letter in my own handwriting.
