I said to Abi Abdillah عليه السلام: what is my condition – I ask you about a matter so you answer me in it with a certain answer, then someone other than me comes to you and you answer him with a different answer? He said: we answer the people with deletion [in-short] and [at other times] with addition [in-depth]. I said: so inform me about the companions of the messenger of Allah صلى الله عليه واله – were they truthful about Muhammad or did they lie? He said: they were truthful, I said: so what was the matter with them that they differed? He said: don’t you know that a man used to come to the messenger of Allah صلى الله عليه واله and ask him about a thing so he answers him in it with an answer, then he answers after that with that which abrogates the former answer, so the narrations abrogated one another.
