"The first Li'an in Islam was when Hilal bin Umayyah accused Sharik bin As-Sahma' (of committing adultery) with his wife. He came to the Prophet and told him about that. The Prophet said: '(Bring) four witnesses, otherwise (you will feel) the Hadd punishment on your back.' And he repeated that several times. Hilal said to him: 'By Allah, O Messenger of Allah! Allah, the Mighty and Sublime, knows that I am telling the truth, and Allah, the Mighty and Sublime, will certainly reveal to you that which will spare my back from the whip.' While they were like that, the Verse of Li'an was revealed to him: 'As to those who accuse their wives.' He called Hilal and he bore witness four times by Allah that he was telling the truth, and the fifth time he invoked the curse of Allah upon him if he were lying. Then he called the woman and she bore witness four times by Allah that he was lying. When it came to the fourth or fifth time, the Messenger of Allah said: 'Stop her, for it will inevitably bring the punishment of Allah upon the liar.' She hesitated until we thought that she was going to confess, then she said: 'I will not dishonor my people today.' Then she went ahead with the oath. The Messenger of Allah said: 'Wait and see. If she produces a child who is white, with straight hair and Qadiy'a eyes, then he belongs to Hilal bin Umayyah, but if she produces a child who is dark with curly hair, of average size and with narrow calves, then he belongs to Sharik bin As-Sahma'.' She produced a child who was dark with curly hair, of average size and with narrow calves. The Messenger of Allah said: 'Had not the matter been settled by the Book of Allah, I would have punished her severely.'"
Sunan an-Nasa'i Book 27, Hadith 81
I was with `Abdullah and Abu Musa; the latter asked the former, "O Abu `Abdur-Rahman! What is
your opinion if somebody becomes Junub and no water is available?" `Abdullah replied, "Do not pray
till water is found." Abu Musa said, "What do you say about the statement of `Ammar (who was
ordered by the Prophet (ﷺ) to perform Tayammum). The Prophet (ﷺ) said to him: "Perform Tayammum and
that would be sufficient." `Abdullah replied, "Don't you see that `Umar was not satisfied by `Ammar's
statement?" Abu- Musa said, "All right, leave `Ammar's statement, but what will you say about this
verse (of Tayammum)?" `Abdullah kept quiet and then said, "If we allowed it, then they would
probably perform Tayammum even if water was available, if one of them found it (water) cold." The
narrator added, "I said to Shaqiq, "Then did `Abdullah dislike to perform Tayammum because of
this?" He replied, "Yes."
Sahih al-Bukhari Book 7, Hadith 13
Allah's Messenger (ﷺ) said, "A lady slave should not be given in marriage until she is consulted, and a virgin
should not be given in marriage until her permission is granted." The people said, "How will she
express her permission?" The Prophet (ﷺ) said, "By keeping silent (when asked her consent)." Some
people said, "If a man, by playing a trick, presents two false witnesses before the judge to testify that
he has married a matron with her consent and the judge confirms his marriage, and the husband is sure
that he has never married her (before), then such a marriage will be considered as a legal one and he
may live with her as husband."
