Allah's Messenger, tell me about the person who found a man with his wife. The remaining part of the hadith is the same (but) with this addition: They invoked curses in the mosque and I was present there. And he narrated in the hadith: He divorced her with three pronouncements before Allah's Messenger (ﷺ) commanded him (to get separation). He separated from her in the presence of Allah's Apostle (ﷺ), whereupon he said: There is a separation between the invokers of curses.
Sahih Muslim Book 19, Hadith 3
← Previous Hadith " And subsequebtly the separation became the practice of al-Mutala'inain." And this addition was also made:" She was pregnant and her son was ascribed to her, and it became customary that such (a son) would inherit her and she would inherit him in the share prescribed by Allah for her.

Sahih Muslim Book 19, Hadith 2 Next Hadith → I was asked about the invokers of curses during the reign of Mus'ab (b. Zubair) whether they could separate (themselves by this process). He said: I did not understand what to say. So I went to the house of Ibn 'Umar (Allah be pleased with them) in Mecca. I said to his servant: Seek permission for Me. He said that he (Ibn 'Umar) had been taking rest. He (Ibn 'Umar) heard my voice. and said: Are you Ibn Jubair? I said: Yes. He'said: Come in. By Allah, it must be some (great) need which has brought you here at this Hour. So I got in and found him lying on a blanket reclining against a pillow stuffed with fibres of date-palm. I said: O Abu'Abd al-Rahman, should there be separation between the invokers of curses? He said: Hallowed be Allah, yes, The first one who asked about it was so and so. he said: Messenger of Allah, tell me If one of us finds his wife committing adultery: what should he do? If he talks, that is something great, and if he keeps quiet that is also (something great) (which he cannot afford to do). Allah's Prophet (ﷺ) kept quiet (or some time). After some time he (that very person) came to him (Allah's Messenger) and said: I have been involved in that very cage about which I had asked you Allah the Exalted and Majestic then revealed (these) verses of Surah Nur:" Those who accuse their wives" (verse 6), and he (the Holy Prophet) recited them to him and admonished him, and exhorted him and informed him that the torment of the world is less painful than the torment of the Hereafter. He said: No, by Him Who sent you with Truth, I did not tell a lie against her. He (the Holy Prophet) then called her (the wife of that person who had accused her) and admonished her, and exhorted her, and informed her that the torment of this world is less painful than the torment of the Hereafter. She said: No, by Him Who sent thee with Truth, he is a liar. (it was) the man who started the swearing of oath and he swore in the name of Allah four times that he was among the truthful. and at the fifth turn he said: Let there be curse of Allah upon him if he were among the liars. Then the woman was called and she swore four times in the name of Allah that he (her husband) was among the liars, and at the fifth time (she said): Let there be curse upon her if he were among the truthful. He (the Holy Prophet) then effected separation between the two.
