It is narrated from Hasan al-Basri (may Allah have mercy on him) that a man secretly married a woman and used to visit her. A neighbor saw this and accused him of adultery. The matter reached Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him), who said: "Present witnesses for the marriage." He replied: "We married secretly and made her family witnesses." Sayyiduna Umar (may Allah be pleased with him) dropped the hadd punishment from the accuser and said: "Protect the chastity of these women, and make marriages public." And he forbade temporary marriage (mut‘ah).
