Sayyidah Zaynab bint Umm Salamah (may Allah be pleased with them both) relates from her mother, Sayyidah Umm Salamah (may Allah be pleased with her), that the Prophet (peace and blessings be upon him) heard the noise of a dispute at the door of Sayyidah Umm Salamah (may Allah be pleased with her), so he (peace and blessings be upon him) came out to them and said: "You bring your disputes to me, yet I am only a human being. Perhaps one of you is more eloquent in presenting his argument than another, and I judge in his favour according to what I hear, thinking him truthful. So whoever I judge in favour of with something of his brother's right, it is a piece of the Fire; let him take it or leave it."
