It is narrated from Sayyiduna Sabrah bin Ma'bad (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) forbade mut'ah and said: "It is unlawful from this day of ours until the Day of Resurrection, and whoever has given something (as dowry) should not take it back."
