"They do not bring any good; they are just a means of taking wealth from the miserly."
Sunan an-Nasa'i Book 35, Hadith 41
← Previous Hadith "In Al-Madinah we used to buy and sell Wasqs (of goods), and we used to call ourselves Samasir (brokers), and the people used to call us like that. The Messenger of Allah came out to us one day, and called us by a name that was better than that which we called ourselves and which the people called us. He said: 'O Tujjar (traders), your selling involves (false) oaths and lies, so mix some charity with it.'"
