Sayyida Umm Kulthum bint Uqbah bin Abi Mu'it (may Allah be pleased with her) narrates that I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "He is not a liar who reconciles between people, so he says good things or spreads good things." She says: I did not hear the Prophet (peace and blessings of Allah be upon him) permit lying except in three cases: to reconcile between people, a husband to his wife, and a wife to her husband.
