Sunan Abi Dawud 2258
سنن أبي داود#2258SahihSa’d bin Jubair said I asked Ibn ‘Umar A man accused his wife of adultery? He said “The Apostle of Allaah(ﷺ) separated the brother and the sister of Banu Al ‘Ajilan (i.e., husband and wife). He said Allaah knows that one of you is a liar, will one of you repent? He repeated these words three times, but they refused. So he separated them from each other
