Asim bin Adi reported,

Ask the Messenger of Allah ﷺ for me, what is your view about a man who finds another man with his wife and kills him? Should he be killed in retaliation, or what should he do?So Asim asked the Messenger of Allah ﷺ about that, and the Messenger of Allah ﷺ disapproved of such questions.Later, Uwaymir met him and asked, "What did you do?"Asim replied, "What I did brought you no good. I asked the Messenger of Allah ﷺ, and he disapproved of such questions."Uwaymir said, "By Allah, I will go to the Messenger of Allah ﷺ myself and ask him."He went to the Messenger of Allah ﷺ and found that revelation had already come down concerning the two of them, so he carried out the lian procedure between them.Uwaymir said, "By Allah, Messenger of Allah, if I were to keep her, I would have lied against her." So he divorced her before the Messenger of Allah ﷺ commanded him to do so, and that became the established practice for the Mutalaineen.Then the Prophet ﷺ said, "Watch her. If she gives birth to a child who is dark-skinned, with deep black eyes and large buttocks, then I can only think that he has spoken the truth about her. But if she gives birth to a reddish child resembling a small lizard, then I can only think that he has lied."She gave birth to a child matching the unfavorable description.

حدثنا أبو مروان العثماني محمد بن عثمان حدثنا إبراهيم بن سعد عن ابن شهاب عن سهل بن سعد الساعدي قال جاء عويمر إلى

عاصم بن عدي فقال

سل لي رسول الله ﷺ أرأيت رجلا وجد مع امرأته رجلا فقتله أيقتل به أم كيف يصنع فسأل عاصم رسول الله ﷺ عن ذلك فعاب رسول الله ﷺ المسائل ثم لقيه عويمر فسأله فقال ما صنعت فقال صنعت أنك لم تأتني بخير سألت رسول الله ﷺ فعاب المسائل فقال عويمر والله لآتين رسول الله ﷺ ولأسألنه فأتى رسول الله ﷺ فوجده وقد أنزل عليه فيهما فلاعن بينهما قال عويمر والله لئن انطلقت بها يا رسول الله لقد كذبت عليها قال ففارقها قبل أن يأمره رسول الله ﷺ فصارت سنة في المتلاعنين ثم قال النبي ﷺ انظروها فإن جاءت به أسحم أدعج العينين عظيم الأليتين فلا أراه إلا قد صدق عليها وإن جاءت به أحيمر كأنه وحرة فلا أراه إلا كاذبا قال فجاءت به على النعت المكروه
