English translation
3501. It was narrated from Anas bin Mâlik that a man at the time of the Messenger of Allâh ﷺ used to buy and sell, but there was some weakness in his intellect. His family came to the Messenger of Allāh ﷺ and said: "O Prophet of Allāh, stop so-and-so, for he buys and sells but there is some weakness in his intellect." The Prophet ﷺ called him, and told him not to buy and sell. He said: "O Messenger of Allāh, I cannot keep away from buying and selling." The Messenger of Allāh ﷺ said: "If you cannot keep away from buying and selling, then say: 'Give and take (on the spot), and no deception.'" (Hasan)
