Sahih al-Bukhari Book 65, Hadith 269
Hilal bin Umaiya accused his wife of committing illegal sexual intercourse with Sharik bin Sahma'
and filed the case before the Prophet. The Prophet (ﷺ) said (to Hilal), "Either you bring forth a proof (four
witnesses) or you will receive the legal punishment (lashes) on your back." Hilal said, "O Allah's
Apostle! If anyone of us saw a man over his wife, would he go to seek after witnesses?" The Prophet (ﷺ)
kept on saying, "Either you bring forth the witnesses or you will receive the legal punishment (lashes)
on your back." Hilal then said, "By Him Who sent you with the Truth, I am telling the truth and Allah
will reveal to you what will save my back from legal punishment." Then Gabriel came down and
revealed to him:--
'As for those who accuse their wives...' (24.6-9) The Prophet (ﷺ) recited it till he reached: '... (her
accuser) is telling the truth.' Then the Prophet (ﷺ) left and sent for the woman, and Hilal went (and
brought) her and then took the oaths (confirming the claim). The Prophet (ﷺ) was saying, "Allah knows
that one of you is a liar, so will any of you repent?" Then the woman got up and took the oaths and
when she was going to take the fifth one, the people stopped her and said, "It (the fifth oath) will
definitely bring Allah's curse on you (if you are guilty)." So she hesitated and recoiled (from taking
the oath) so much that we thought that she would withdraw her denial. But then she said, "I will not
dishonor my family all through these days," and carried on (the process of taking oaths). The Prophet (ﷺ)
then said, "Watch her; if she delivers a black-eyed child with big hips and fat shins then it is Sharik
bin Sahma's child." Later she delivered a child of that description. So the Prophet (ﷺ) said, "If the case
was not settled by Allah's Law, I would punish her severely."
A man came to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Suppose a man saw another man with his wife, should he kill him whereupon you might kill him (i.e. the killer) (in Qisas) or what should he do?" So Allah revealed concerning their case what is mentioned of the order of Mula'ana. Allah's Apostle said to the man, "The matter between you and your wife has been decided." So they did Mula'ana in the presence of Allah's Messenger (ﷺ) and I was present there, and then the man divorced his wife. So it became a tradition to dissolve the marriage of those spouses who were involved in a case of Mula'ana. The woman was pregnant and the husband denied that he was the cause of her pregnancy, so the son was (later) ascribed to her. Then it became a tradition that such a son would be the heir of his mother, and she would inherit of him what Allah prescribed for her.
A man accused his wife of illegal sexual intercourse and denied his paternity to her (conceived) child during the lifetime of Allah's Messenger (ﷺ). Allah's Messenger (ﷺ) ordered them both to do Mula'ana as Allah decreed and then gave his decision that the child would be for the mother, and a divorce decree was issued for the couple involved in a case of Mula'ana.
