Abu Rafi’ (may Allah be pleased with him) narrated that the Messenger of Allah (ﷺ) said: “I should not find any one of you reclining on his couch, and when a command of mine comes to him, whether I have ordered something or forbidden something, he says: ‘We do not know; we will follow only what we find in the Book of Allah.’”
