This Hadīth informs us that ‘Uwaymir al-‘Ajlāni (may Allah be pleased with him) asked about the ruling regarding the man who sees another man sleeping with his wife, and what he should do. The Prophet (may Allah's peace and blessings be upon him) disliked to tackle such an issue, given the unpleasant aspects involved therein. ‘Uwaymir, however, insisted on posing this question, which was concerning a matter that had actually happened to him. So, he went to the Prophet (may Allah's peace and blessings be upon him) and asked about the ruling regarding his case. In response, the Prophet (may Allah's peace and blessings be upon him) informed ‘Uwaymir that Allah, the Almighty, revealed Qur’an containing the judgment on their case. Thereupon, he and his wife engaged in Li‘ān. ‘Uwaymir (may Allah be pleased with him) did not know that Li‘ān would automatically make his wife forbidden for him, so he pronounced divorce three times against her. This was the first case of Li‘ān in Islam.
