The Shariah has clarified the rulings of marriage between the man and the woman and has explained the rulings of the husband's accusation of his wife for committing adultery without evidence and the consequent practice of Li‘ān, besides other rulings of separation, to protect lineages, repel shame from the spouses, and ward off the legally prescribed punishment of Qadhf (false accusation of adultery). In this Hadīth, ‘Abdullah ibn Mas‘ūd (may Allah be pleased with him) narrates that they were in the Prophet's mosque on Friday night when a man from the Ansār - the people of Madīnah - came. It was Hilāl ibn ’Umayyah, and it is said: ‘Uwaymir al-‘Ajlāni. He said: "If a man found another man with his wife," i.e., he saw her committing adultery with him. If "he speaks" about it, "you will flog him" inflicting on him the legally prescribed punishment of Qadhf for having no witnesses, and if "he kills" the adulterer, "you will kill him" by way of legal retribution. "And if he remains silent" and does nothing, "he will remain silent in anger," i.e., anger and hatred for her. It seems that the man's speech was before the revelation of the verses of Li‘ān and it also seems that it was a mere question posed by that man at that time, not a real incident that had already occurred. The Messenger of Allah (may Allah's peace and blessings be upon him) used to hate such questions as mentioned in the Hadīth of Sahl ibn Sa‘d in the two Sahīh Collections. Then, this man swore to ask the Messenger of Allah (may Allah's peace and blessings be upon him) about this matter. On the next day - the next morning - the man went to the Messenger of Allah (may Allah's peace and blessings be upon him) asking about what was previously mentioned. Thereupon, the Prophet (may Allah's peace and blessings be upon him) supplicated: "O Allah, judge," i.e., clarify to us the ruling in this regard, and he continued supplicating Allah Almighty to clarify this incident, so, the verses of Li‘ān were revealed. These are the verses in which Allah Almighty says: {As for those who accuse their wives [of adultery] but have no witnesses except themselves, then the evidence of one of them is to testify four times by Allah that he is telling the truth, and the fifth [oath] is that may Allah curse him if he is telling a lie. But she will be spared the punishment if she testifies four times by Allah that he is telling a lie, and the fifth [oath] is that may Allah’s wrath be upon her if he is telling the truth.} [Surat an-Nūr: 6-9] This means: Men who accuse their wives without having witnesses besides their own selves to testify to the truthfulness of their accusation, each of them should swear four times by Allah that he is telling the truth about accusing his wife of adultery. Then, in the fifth testimony, he should add the supplication against himself of being worthy of condemnation if he is lying about his accusation, which makes her subject to the legally prescribed punishment of adultery. What spares her of this punishment is to testify four times by Allah that he is lying about accusing her. Then, in her fifth testimony, she should add the supplication against herself of being liable for Allah's wrath if he is telling the truth about what he accuses her of. Among all people, this man was afflicted by the occurrence of what he asked about to his wife. So, he accompanied his wife to the Messenger of Allah (may Allah's peace and blessings be upon him). They both swore the oath of condemnation, i.e., the man testified four times by Allah that he was telling the truth, and then, the fifth time, he invoked the curse of Allah upon himself if he was lying. This is because testimony in an adultery case is not complete except with four witnesses, but this case was witnessed by none except the husband; hence, he was assigned four testimonies so that each oath would replace a witness, as an oath could sometimes replace a witness like when someone is entitled to some right but has one witness only. In this case, the Shariah considers his oath in place of the witness. After completing the four testimonies that replace the four witnesses, nothing is left after the testimony of the four witnesses in adultery against the married person, as in this case, except stoning, which is death. There is nothing left after taking the oath of condemnation four times except the curse of Allah Almighty or His wrath, which also indicates death (ruin). The woman, then, went to swear the oath of condemnation, but the Prophet (may Allah's peace and blessings be upon him) said to her: "Stop," a word meant here to deter her, i.e., refrain and take your time. However, she refused to stop or be dissuaded from completing Li‘ān. Hence, she took her part in Li‘ān. When the two parties swore the oath of condemnation and went away after finishing their testimonies, the Messenger of Allah (may Allah's peace and blessings be upon him) said: "Perhaps she will give birth to" the baby in her womb, and he will be "a curly-haired black child," i.e., not straight-haired, which was the description of the one she was accused of committing adultery with. It is as if the Prophet (may Allah's peace and blessings be upon him) most likely believed that she was lying, and the child she gave birth to was just as the Prophet (may Allah's peace and blessings be upon him) had described. The Hadīth clarifies that the ruling of Li‘ān, in principle, is to take place between the man and his wife if he accuses her of adultery and has no witness but himself. It also points out that things must be judged according to what is apparent, whereas Allah Almighty is the One Who judges the intentions. It explains how Li‘an must take place in the presence of the Imam or the judge and in the presence of an assembly of people. It shows the condition that makes Li‘ān obligatory, which is the woman's denial of committing adultery because if she admits it, Li‘ān becomes impermissible and she becomes subject to the legally prescribed punishment. It also signifies that it is Sunnah for the ruler to admonish the two persons involved in Li‘ān when intending to swear the oath of condemnation, which becomes confirmed after the fifth time..
