'Uwaimir came to ʿAsim bin ʿAdi who was the chief of Bani Ajlan and said, "What do you say about a man who has found another man with his wife? Should he kill him whereupon you would kill him (i.e. the husband), or what should he do? Please ask Messenger of Allah ﷺ about this matter on my behalf." ʿAsim then went to the Prophet ﷺ and said, "O Messenger of Allah ﷺ! (And asked him that question) but Messenger of Allah ﷺ disliked the question," When 'Uwaimir asked ʿAsim (about the Prophet's answer) ʿAsim replied that Messenger of Allah ﷺ disliked such questions and considered it shameful. "Uwaimir then said, "By Allah, I will not give up asking unless I ask Messenger of Allah ﷺ about it." Uwaimir came (to the Prophet ) and said, "O Messenger of Allah ﷺ! A man has found another man with his wife! Should he kill him whereupon you would kill him (the husband, in Qisas) or what should he do?" Messenger of Allah ﷺ said, "Allah has revealed regarding you and your wife's case in the Qur'an "So Messenger of Allah ﷺ ordered them to perform the measures of Mula'ana according to what Allah had mentioned in His Book. So 'Uwaimir did Mula'ana with her and said, "O Messenger of Allah ﷺ! If I kept her I would oppress her." So 'Uwaimir divorced her and so divorce became a tradition after them for those who happened to be involved in a case of Mula'ana. Messenger of Allah ﷺ then said, "Look! If she (Uwaimir's wife) delivers a black child with deep black large eyes, big hips and fat legs, then I will be of the opinion that 'Uwaimir has spoken the truth; but if she delivers a red child looking like a Wahra then we will consider that 'Uwaimir has told a lie against her." Later on she delivered a child carrying the qualities which Messenger of Allah ﷺ had mentioned as a proof for 'Uwaimir's claim; therefore the child was ascribed to its mother henceforth.
