I was imprisoned with Imam Hasan Askari (a.s) in the prison of Mohtadi bin Wathiq. Imam (a.s) said to me: O Aba Hashim, this transgressor wanted to play with divine destiny, but Allah, the Mighty and the High has cut off his life and transferred his kingdom to his successors. I don’t have a son at present; but very soon, I will be bestowed with one. Abu Hashim said: The following morning Turks attacked Mohtadi and slew him and Motamid succeeded him to the throne. Almighty Allah saved us from the intrigue of Mohtadi also.
