It was narrated from Anas bin Malik (RA) that there was a man at the time of the Messenger of Allah ﷺ whose mental faculties were lacking, and he used to buy and sell. His family came to the Prophet ﷺ and said, "O Messenger of Allah, stop him." So the Prophet ﷺ called him, and told him not to do that. He said: "O Messenger of Allah, I cannot bear to be away from business," He said, "If you engage in a transaction, then say: Take it (i.e. the goods) and dont cheat (me).”
