Abdullah bin Abbas reported,

The matter of liʿan (mutual cursing) was mentioned in the presence of the Prophet ﷺ. Asim bin Adi made a statement about it and then departed. A man from his people came to him complaining that he had found another man with his wife. Asim said, "I have only been tested with this because of what I said."He took the man to the Prophet ﷺ and informed him of what he had found with his wife. That husband was pale-yellow in complexion, lean of flesh, with straight hair, while the man he accused of being with his wife was dark-skinned, sturdy, and full of flesh.The Prophet ﷺ said, "O Allah, make it clear."She gave birth to a child resembling the man whom her husband had named. So the Prophet ﷺ carried out the liʿan between them.A man in the gathering said to Ibn Abbas, "Is she the one about whom the Prophet ﷺ said, 'Had I stoned anyone without proof, I would have stoned this one'?"Ibn Abbas replied, "No. That was another woman who used to display immorality openly while professing Islam."Abu Salih and Abdullah bin Yusuf said, khadhla (meaning sturdy of build).

عن ابن عباس

أنه ذكر التلاعن عند النبي ﷺ فقال عاصم بن عدي في ذلك قولا ثم انصرف، فأتاه رجل من قومه يشكو إليه أنه قد وجد مع امرأته رجلا، فقال عاصم: ما ابتليت بهذا إلا لقولي. فذهب به إلى النبي ﷺ فأخبره بالذي وجد عليه امرأته، وكان ذلك الرجل مصفرا، قليل اللحم، سبط الشعر، وكان الذي ادعى عليه أنه وجده عند أهله آدم خدلا كثير اللحم، فقال النبي ﷺ: اللهم بين، فجاءت شبيها بالرجل الذي ذكر زوجها أنه وجده، فلاعن النبي ﷺ بينهما. قال رجل لابن عباس في المجلس: هي التي قال النبي ﷺ لو رجمت أحدا بغير بينة لرجمت هذه؟ فقال: لا، تلك امرأة كانت تظهر في الإسلام السوء. قال أبو صالح وعبد الله بن يوسف: خذلا.
