Ibn 'Umar (RA) reported: Allah's Messenger ( صلی اللہ علیہ وسلم ) asked a person from the Ansar and his wife to invoke curse (upon one another in order to testify to their truthfulness), and then effected separation between them.

A hadith like this has been narrated on the authority of 'Ubaidulah with the same chain of transmitters.

'Abdullah reported: We were on the night of Friday staying in the mosque when a person from the Ansar came there and said: If a person finds his woman along with a man, and he speaks about it, you would lash him, and if he kills, you will kill him, and if he keeps quiet he shall have to consume anger. By Allah, I will definitely ask about him from Allah's Messenger ( صلی اللہ علیہ وسلم ) . On the following day he came to Allah's Messenger ( صلی اللہ علیہ وسلم ) and asked him thus: If a man were to find with his wife a man and if he were to talk about it, you would lash him; and if he killed, you would kill him, and if he were to keep quiet, he would consume anger, whereupon he (the Holy Prophet) said: Allah, solve (this problem), and he began to supplicate (before Him), and then the verses pertaining to li'an were revealed: "Those who accuse their wives and have no witnesses except themselves" (xxiv. 6). The person was then put to test according to these verses in the presence of the people. There came he and his wife in the presence of Allah's Messenger ( صلی اللہ علیہ وسلم ) , and they invoked curses (in order to testify their claim). The man swore four times in the name of Allah that he was one of the truthful and then invoked curse for the fifth time saying: Let there be curse of Allah upon him if he were among the liars. Then she began to invoke curse. Allah's Messenger ( صلی اللہ علیہ وسلم ) said to her: just wait (and curse after considering over it), but she refused and invoked curse and when she turned away, he (Allah's Apostle) ( صلی اللہ علیہ وسلم ) said: It seems that this woman shall give birth to a curly-haired black child, and so she did gave birth to a curly-haired black child.

A hadith like this is narrated on the authority of A'mash.

Muhammad (one of the narrators) reported: I asked Anas bin Malik (RA) knowing that he had a knowledge of (the case of li'an). He said: Hilal bin Umayya (RA) accused his wife with the charge of fornication with Sharik bin Sahma, the brother of al-Bara'b Malik from the side of his mother. And he was the first person who invoked curse (li'an) in Islam. He in fact invoked curse upon her. Allah's Messenger ( صلی اللہ علیہ وسلم ) said: See to her if she gives birth to a white-complexioned child having dark hair and bright eyes; he must be the son of Hilal bin Umayya; and if she gives birth to a child with dark eyelids, curly hair and lean shanks, he must be the offspring of Sharik bin Sahma. He said: I was informed that she gave birth to a child having dark eyelids, curly hair and lean shanks.

Ibn Abbas (RA) reported: Mention was made of li'an in the presence of Allah's Messenger ( صلی اللہ علیہ وسلم ) . And Asim bin 'Adi passed a remark about it and then turned away, and a man of his tribe came to him complaining that he had found a man with his wife, whereupon 'Asim said: I have been taken by my words. He took him to Allah's Messenger ( صلی اللہ علیہ وسلم ) and told him about the man whom he had found with his wife and this man was a lean, yellow-coloured man with lank hair, and the person who was accused of committing adultery with her (his wife) had fleshy shanks, with wheat complexion and heavy bulk. Allah's Messenger ( صلی اللہ علیہ وسلم ) said: O Allah, make (this case) manifest. And as she gave birth to a child, whose face resembled that person about whom her husband had made mention that he had found her with, and Allah's Messenger ( صلی اللہ علیہ وسلم ) had asked them to invoke curses. A person said to Ibn 'Abbas (RA): Is she (that woman) about whom Allah's Messenger (may peace be upen him) (said): "If I were to stone anybody without evidence, I would have stoned her"? Ibn 'Abbas (RA) said: No, it is not she. That woman was one who openly spread evil in society. This hadith has been narrated on the authority of Ibn 'Abbas (RA) through another chain of transmitters with the addition of these words: 'With flesh, and curly tangled hair."

'Abdullah b Shaddad reported that mention was made about the invokers of curses before Ibn 'Abbas (RA) . Ibn Shaddad said: Are these the two about whom Allah's Apostle ( صلی اللہ علیہ وسلم ) said. "If I were to stone one without evidence, I would have definitely stoned her"? Ibn Abbas (RA) said: She is not this woman; but she is the one who (committed adultery) openly.

Abu Hurairah (RA) reported that Sa'd bin 'Ubadah al-Ansari said: Messenger of Allah, tell me if a man finds his wife with another person, should he kill him? Allah's Messenger ( صلی اللہ علیہ وسلم ) said: No. Sa'd said: Why not? I swear by Him Who has honoured you with Truth. There upon Allah's Messenger ( صلی اللہ علیہ وسلم ) said: Listen to what your chief says.

Abu Hurairah (RA) reported that Sa'd bin 'Ubadah al-Ansari said: Messenger of Allah, tell me if a man finds his wife with another person, should he kill him?

Abu Hurairah (RA) reported that Sa'd bin Ubadah (RA) said: Messenger of Allah, if I were to find with my wife a man, should I wait until I bring four witnesses? He said: Yes.
