Muhammad b. Ali Majiluwayh narrated to us from his uncle Muhammad b. Abi'l Qasim from Ahmad b. Muhammad b. Khalid from his father from Muhammad b. Yahya al-Khazzaz from Ghiyath b. Ibrahim from al-Sadiq Jafar b. Muhammad from his father from his forefathers .

He said: Amir al-Mu'minin said: I will describe Islam in a way that no one before me nor after me has described it: Islam is submission, and submission is sincerity, and sincerity is certainty, and certainty is performance, and performance is [good] action. The believer takes his religion from his Lord and not his opinion. O people! Your religion, your religion! Hold onto it, and do not allow anyone to hinder you or remove you from it. A sin in Islam is better than a good deed in other religions, for a sin in Islam can be forgiven, while a good deed in another religion is not accepted.
