1. It was narrated to me by Muhammad b. Musa b. al-Mutawakil who said it was narrated to me by Abu al-Hassan al-Asadi who said it was narrated to me by Muhammad b. al-Hussain al-Sufi from Yusif b. ’Aqeel from Ishaq b. Rahawayh who said: When Imam Reza (a.s.) reached Nishapur and intended to go to Mamoon, the narrators of traditions gathered around him and said, “O son of Allah’s Messenger! You are leaving us without having said any tradition, which could benefit us.” Imam (a.s.) was seated in the camel saddle. He put his head out and said, “I heard my father, Musa Ibne Ja’far (a.s.), who says he heard from his father, Ja’far Ibne Muhammad (a.s.), who says he heard from his father, Muhammad Ibne Ali (a.s.), who says he heard from his father, Ali Ibne Husain (a.s.), who says he heard from his father, Husain Ibne Ali (a.s.), who says he heard from his father, Amirul Momineen Ali Ibne Abi Talib (a.s.), who says he heard from the Messenger of Allah (s.a.w.s.), who says he heard from Jibraeel, who says he heard from Almighty Allah that, ‘The statement Laa ilaaha illallaah is My fort. One who enters My fort will remain safe from My punishment.” When they moved on, he loudly said: “There are certain conditions for this. And I am one of these conditions.”
