It was narrated that Qais bin Abi Gharazah said: "At the time of the Messenger of Allah (صلی اللہ علیہ و آلہ سلم) we used to be called Samasir (brokers). The Messenger of Allah (صلی اللہ علیہ و آلہ سلم) came to us when we were selling and called us by a name that was better than that. He said: O merchants (Tujjar), this selling involves lies and (false) oaths, so mix some charity with it.
