Imam Muhammad bin Sirin, may Allah have mercy on him, said: In the beginning, people did not ask about the chain of narration, then they started asking (i.e., they began to inquire about who the narrator is and what he is like). If the narrator was a follower of the Sunnah, they would accept the hadith from him, and if he was not a follower of the Sunnah, they would not accept the hadith from him. Imam Darimi said: I do not think that Jarir heard this from Asim.
