I said to Ibn `Umar, "If a man accuses his wife of illegal sexual intercourse (what is the judgment)?"He said, "Allah's Prophet separated the couple of Bani 'Ajlan (when the husband accused his wife foran illegal sexual intercourse). The Prophet (ﷺ) said, 'Allah knows that one of you two IS a liar; so will oneof you repent?' But they refused. He then again said, 'Allah knows that one of you two is a liar; so willone of you repent?' But they refused, whereupon he separated them by divorce." Aiyub (a subnarrator)said: `Amr bin Dinar said to me, "In the narration there is something which I do not see youmentioning, i.e. the husband said, "What about my money (Mahr)?' The Prophet (ﷺ) said, "You are notentitled to take back money, for if you told the truth you have already entered upon her (andconsummated your marriage with her) and if you are a liar then you are less entitled to take it back.
