Sayyida Umm Kulthum bint Uqbah (may Allah be pleased with her) narrates: She heard the Prophet Muhammad (peace be upon him) say: "That person is not a liar who (by misstatement) reconciles between people; that person intends to spread goodness (the narrator is in doubt, perhaps these are the words), he speaks words of goodness."
