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).

Hazrat Urwah bin Zubair (may Allah have mercy on him) said: "Indeed, secret marriage is forbidden."

The Messenger of Allah (peace and blessings be upon him) said: "The distinction between the lawful and the unlawful is the sound and the beating of the drum."

When Sayyiduna Umar bin Khattab (may Allah be pleased with him) heard the sound of takbeer from a place, he asked: "What is this?" It was said: "A marriage is taking place." He said: "Make the marriage public."

Hazrat Abu Salamah bin Abdur Rahman (may Allah have mercy on him) said: "On the wedding night of Abdur Rahman bin Awf (may Allah be pleased with him), the duff was beaten over his head and singing was done."

Muhammad bin Sirin (may Allah have mercy on him) said: "News reached me that whenever Umar bin Khattab (may Allah be pleased with him) heard a sound and disliked it, he would inquire about it. If it was said that it was a wedding or a circumcision, he would remain silent."

It is narrated from Hasan al-Basri (may Allah have mercy on him) that a man performed a secret marriage. Someone accused him, saying, "You are committing adultery." The matter was brought to Sayyiduna Umar ibn al-Khattab (may Allah be pleased with him), so the man said, "She is my wife." Thus, Sayyiduna Umar (may Allah be pleased with him) did not carry out the hadd punishment on the accuser.

It is narrated from Hazrat Ata (may Allah have mercy on him) that if someone says to another: "You have unlawful relations with your wife," then there is no hadd (prescribed punishment) for this.

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Make the marriage public and beat the tambourine (duff) on it."
