(3) Ibn Mahboob narrated from Abu Ayyoob al-Khazzaz that Muhammad bin Muslim had said: I asked Abu Ja’far as-Sadiq : What about one, who denies an imam of you? He said: “He, who denies an imam appointed by Allah and exempt himself from him and his faith, is apostate and unbeliever because the imam is appointed by Allah and his religion is the religion of Allah; therefore whoever denies the religion of Allah, is to be killed except if he turns to Allah in repentance of what he has said or done.”
