39-2 Abu Nasr Ahmad ibn Al-Husayn ibn Ahmad ibn Obayd al-Dhabbi narrated that he had heard that Abul Husayn ibn Ahmad quote on the authority of his grandfather, on the authority of his father, “When Ali ibn Musa Ar-Ridha’  entered Neishaboor at the time of Al-Ma’mun, I was at his service and took care of his needs as long as he was there until he departed towards Sarakhs. I accompanied him. I accompanied him when he wanted to leave Sarakhs to go to Marv. But as soon as we passed through one way-station, he brought out his head from his carriage andsaid, “O Aba Abdullah! Return. May you be successful. You have performed what is incumbent upon you. You need not accompany me anymore.” I said, “I swear by al-Mustafa (the Prophet), al-Mortadha (Imam Ali) and az-Zahra (Fatima). Please tell me one tradition to heal me so that I may return.” He said, “Are you asking me for traditions? I have left the neighborhood of my grandfather - the Prophet of God  - not knowing what will happen to my affairs.” I said, “I swear by al-Mustafa, al-Mortadha and az-Zahra. Please tell me one tradition to heal me so that I may return.” Then he said, “My father  narrated that his father  quoted on the authority of his father  that he had heard his forefathers  say that they heard their forefathers  say that they heard Ali ibn Abi Talib  say that he had heard the Prophet (S) say that God - the Exalted the Magnificent - said, There is no god but God is My Name. Whoever says it sincerely and whole-heartedly will enter My Stronghold. Whoever enters My Stronghold is secure from My punishment.”The author of this book (a.s.heikh Sadooq) - may God forgive him - said, “Sincerity here means that these words should protect him from saying what God the Exalted the Honorable has forbidden.
