He informed him that Uwaymir al-Ajlani came to Asim bin Adi al-Ansari and said to him, "Tell me, Asim, if a man finds another man with his wife, should he kill him, in which case you would execute him, or what should he do? Ask the Messenger of Allah ﷺ about this for me, Asim."So Asim asked the Messenger of Allah ﷺ, but the Messenger of Allah ﷺ disliked such questions and found them objectionable, so much so that what Asim heard from the Messenger of Allah ﷺ weighed heavily upon him.When Asim returned to his family, Uwaymir came to him and asked, "Asim, what did the Messenger of Allah ﷺ say to you?"Asim replied to Uwaymir, "You have brought me no good. The Messenger of Allah ﷺ disliked the question I asked him."Uwaymir said, "By Allah, I will not stop until I ask him about it myself."So Uwaymir went forward until he came to the Messenger of Allah ﷺ in the midst of the people and said, "Messenger of Allah, tell me about a man who finds another man with his wife. Should he kill him, in which case you would execute him, or what should he do?"The Messenger of Allah ﷺ said, "Revelation has come down concerning you and your wife. Go and bring her."Sahl said, So they performed the mutual cursing, and I was among the people with the Messenger of Allah ﷺ. When they had finished, Uwaymir said, "I would have lied about her, Messenger of Allah, if I were to keep her." So he divorced her three times before the Messenger of Allah ﷺ could instruct him to do so.Ibn Shihab said, This became the established practice for those who undergo mutual cursing.
و حدثنا يحيى بن يحيى قال قرأت على مالك عن ابن شهاب أن
أخبره أن عويمرا العجلاني جاء إلى عاصم بن عدي الأنصاري فقال له أرأيت يا عاصم لو أن رجلا وجد مع امرأته رجلا أيقتله فتقتلونه أم كيف يفعل فسل لي عن ذلك يا عاصم رسول الله ﷺ فسأل عاصم رسول الله ﷺ فكره رسول الله ﷺ المسائل وعابها حتى كبر على عاصم ما سمع من رسول الله ﷺ فلما رجع عاصم إلى أهله جاءه عويمر فقال يا عاصم ماذا قال لك رسول الله ﷺ قال عاصم لعويمر لم تأتني بخير قد كره رسول الله ﷺ المسألة التي سألته عنها قال عويمر والله لا أنتهي حتى أسأله عنها فأقبل عويمر حتى أتى رسول الله ﷺ وسط الناس فقال يا رسول الله أرأيت رجلا وجد مع امرأته رجلا أيقتله فتقتلونه أم كيف يفعل فقال رسول الله ﷺ قد نزل فيك وفي صاحبتك فاذهب فأت بها قال سهل فتلاعنا وأنا مع الناس عند رسول الله ﷺ فلما فرغا قال عويمر كذبت عليها يا رسول الله إن أمسكتها فطلقها ثلاثا قبل أن يأمره رسول الله ﷺ قال ابن شهاب فكانت سنة المتلاعنين
