#3142 Al-Hasan bin Bishr informed us, saying: My father narrated to me, from Sufyan, from Thuwayr, from Yahya bin Ja'dah, from Ali (may Allah be pleased with him), who said: "O carriers of knowledge, act upon it, for the scholar is only the one who acts upon what he knows and whose knowledge conforms to his actions. There will be people who carry knowledge that does not go beyond their collarbones; their actions contradict their knowledge, and their private secrets contradict their public appearances. They sit in circles, boasting to one another, until a man becomes angry with his companion for sitting with someone else and leaving him. Those are the ones whose deeds in those sittings of theirs do not ascend to Allah, the Exalted."
