Read all Ahadith in the book of invoking curses by sahih al muslim

Sahl b. Sa'd al-Sa'idi reported that'Uwaimir al-'Ajlani came to 'Asim b. 'Adi al-Ansari and said to him. Tell me about a person who finds a man with his wife; should he kill him, and be killed In retaliation; or how should he act? 'Asim, ask for me (religious verdict about it) from Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). So 'Asim asked Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and he did not like this question and he disapproved of it so much that'Asim felt aggrieved at what he had heard from Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). When 'Asim came back to his family, 'Uwaimir came to him and said: 'Asim, what did Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) say to you? 'Asim said to 'Uwaimir: You did not bring something good. Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) did not like this religious verdict that I sought from him. 'Uwaimir said: By Allah, I will not rest until I have asked him about it. 'Uwaimir proceeded until he came to Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) as he was sitting amidst people, and said: Messenger of Allah, tell me about a person who found a man with his wife. Should he kill him, and then you would kill him, or how should he act? Thereupon Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) said: (Verses) have been revealed concerning you and your wife; so go and bring her. Sahl said that they both invoked curses (and further said): I was along with people in the company of Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ). And when they had finished, Uwaimir said: Allah's Messenger, I shall have told a lie against her if I keep her (now). So he divorced her with three pronouncements before Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) had commanded him. Ibn Shihab said: Subsequently that was the practice of invokers of curses (al Mutala'inain)

Sahl b. Sa'd reported.. 'Uwaimir al-Ansari (Allah be pleased with him) from Banu'l-'Ajlan came to 'Asim b. 'Adi (Allah be pleased with him) the remaining part of the hadith is the same and it was also reecorded in it: 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.

Ibn Shihab narrated about the invokers of curses and the practice of (li'an) based on the authority of Sahl b. Sa'd, of the tribe of Sa'ida. that a person from the Ansar came to Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) and said: 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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) commanded him (to get separation). He separated from her in the presence of Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ), whereupon he said: There is a separation between the invokers of curses.

Sa'id b Jubair reported: 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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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. حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ، حَدَّثَنَا أَبِي ح، وَحَدَّثَنَا أَبُو بَكْ

A hadith like this is narrated by Ibn Numair with a slight variation of words.

Ibn Umar (Allah be pleased with them) reported Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) saying to the invokers of curse: Your account is with Allah. One of you must be a liar. You have now no right over this woman. He said: Messenger of Allah, what about my wealth (dower that I paid her at the time of marriage)? He said: You have no claim to wealth. If you tell the truth, it (dower) is the recompense for your having had the right to intercourse with her, and if you tell a lie against her, it is still more remote from you than she is. Zuhair said in his narration: Sufyan reported to us on the authority of 'Amr that he had heard Sa'id b Jubair saying: I heard Ibn Umar (Allah be pleased with them) saying that Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) had said it.

Ibn 'Umar (Allah be pleased with them) said that Allah's Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) effected separation between the two members of Banu al-'Ajlan, and said: Allah knows that one of you is a liar. Is there one to repent among you?

Sa'id b. Jubair reported: I asked Ibn 'Umar (Allah be pleased with them) about invoking curse (li'an), and he narrated Similarly from Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ).

Sa'id b. Jubair reported that Mus'ab b. Zubair did not effect separation between the Mutala'inain (invokers of curses). Sa'id said: It was mentioned to 'Abdullah b. Umar (Allah be pleased with them) and he said: Allah's Apostle ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) effected separation between the two members of Banu al-'Ajlan.

Nafi' reported on the authority of Ibn Umar (Allah be pleased with them) that a person invoked curse on the wife during the lifetime of Allah s Messenger ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ), so he effected separation between them and traced the lineage of the son to his mother.
