It is narrated from Hazrat Suwaid bin Qais (may Allah be pleased with him) that I and Makhrifah Abdi together imported cloth from a place called "Hajar." We presented ourselves before the Prophet Muhammad (peace and blessings be upon him). The Prophet (peace and blessings be upon him) bargained with us over a pair of trousers. At that time, there were some people with us who used to weigh out the money, giving it by weight. The Prophet (peace and blessings be upon him) said to the one who weighed, "Weigh out the money for them and weigh it accurately."
