These were the battles of Allah's Messenger (ﷺ) (which he fought), and while mentioning (the Badr battle) he
said, "While the corpses of the pagans were being thrown into the well, Allah's Messenger (ﷺ) said (to them),
'Have you found what your Lord promised true?" `Abdullah said, "Some of the Prophet's companions
said, "O Allah's Messenger (ﷺ)! You are addressing dead people.' Allah's Messenger (ﷺ) replied, 'You do not hear
what I am saying, better than they.' The total number of Muslim fighters from Quraish who fought in
the battle of Badr and were given their share of the booty, were 81 men." Az-Zubair said, "When their
shares were distributed, their number was 101 men. But Allah knows it better."
Sahih al-Bukhari Book 64, Hadith 75
When `Abdullah bin Ubai (the chief of hypocrites) died, his son came to the Prophet (ﷺ) and said, "O
Allah's Messenger (ﷺ)! Please give me your shirt to shroud him in it, offer his funeral prayer and ask for
Allah's forgiveness for him." So Allah's Messenger (ﷺ) (p.b.u.h) gave his shirt to him and said, "Inform me
(When the funeral is ready) so that I may offer the funeral prayer." So, he informed him and when the
Prophet intended to offer the funeral prayer, `Umar took hold of his hand and said, "Has Allah not
forbidden you to offer the funeral prayer for the hypocrites? The Prophet (ﷺ) said, "I have been given the
choice for Allah says: '(It does not avail) Whether you (O Muhammad) ask forgiveness for them
(hypocrites), or do not ask for forgiveness for them. Even though you ask for their forgiveness seventy
times, Allah will not forgive them. (9.80)" So the Prophet (ﷺ) offered the funeral prayer and on that the
revelation came: "And never (O Muhammad) pray (funeral prayer) for any of them (i.e. hypocrites)
that dies." (9. 84)
Sahih al-Bukhari Book 23, Hadith 30
"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.'"
