On the day of Al-Khandaq (the battle of trench.) `Umar bin Al-Khattab came cursing the disbelievers of Quraish after the sun had set and said, "O Allah's Apostle I could not offer the `Asr prayer till the sun had set." The Prophet said, "By Allah! I, too, have not prayed." So we turned towards Buthan, and the Prophet performed ablution and we too performed ablution and offered the `Asr prayer after the sun had set, and then he offered the Maghrib prayer.

I heard Allah's Apostle, in the year of the Conquest of Mecca, saying, "Allah and His Apostle made illegal the trade of alcohol, dead animals, pigs and idols." The people asked, "O Allah's Apostle! What about the fat of dead animals, for it was used for greasing the boats and the hides; and people use it for lights?" He said, "No, it is illegal." Allah's Apostle further said, "May Allah curse the Jews, for Allah made the fat (of animals) illegal for them, yet they melted the fat and sold it and ate its price."

(the wife of the Prophet) A group of Jews entered upon the Prophet and said, "As-Samu-Alaikum." (i.e. death be upon you). I understood it and said, "Wa-Alaikum As-Samu wal-la'n. (death and the curse of Allah be Upon you)." Allah's Apostle said "Be calm, O `Aisha! Allah loves that on, should be kind and lenient in all matters." I said, "O Allah's Apostle! Haven't you heard what they (the Jews) have said?" Allah's Apostle said "I have (already) said (to them) "And upon you ! "

The Jews used to greet the Prophet by saying, "As-Samu 'Alaika (i.e., death be upon you), so I understood what they said, and I said to them, "As-Samu 'alaikum wal-la'na (i.e. Death and Allah's Curse be upon you)." The Prophet said, "Be gentle and calm, O `Aisha, as Allah likes gentleness in all affairs." I said, "O Allah's Prophet! Didn't you hear what they said?" He said, "Didn't you hear me answering them back by saying, 'Alaikum (i.e., the same be upon you)?"

The Prophet said, "A group of Israelites were lost. Nobody knows what they did. But I do not see them except that they were cursed and changed into rats, for if you put the milk of a she-camel in front of a rat, it will not drink it, but if the milk of a sheep is put in front of it, it will drink it." I told this to Ka`b who asked me, "Did you hear it from the Prophet ?" I said, "Yes." Ka`b asked me the same question several times.; I said to Ka`b. "Do I read the Torah? (i.e. I tell you this from the Prophet.)"

I heard Az-Zuhri saying, "I heard `Urwa bin Az-Zubair. Sa`id bin Al-Musaiyab, 'Alqama bin Waqqas and 'Ubaidullah bin `Abdullah each narrating part of the narrative concerning `Aisha the wife of the Prophet. `Aisha said: When I and Um Mistah were returning, Um Mistah stumbled by treading on the end of her robe, and on that she said, 'May Mistah be ruined.' I said, 'You have said a bad thing, you curse a man who took part in the battle of Badr!." Az-Zuhri then narrated the narration of the Lie (forged against `Aisha).

When it was the day of Uhud, the pagans were defeated. Then Satan, Allah's Curse be upon him, cried loudly, "O Allah's Worshippers, beware of what is behind!" On that, the front files of the (Muslim) forces turned their backs and started fighting with the back files. Hudhaifa looked, and on seeing his father Al-Yaman, he shouted, "O Allah's Worshippers, my father, my father!" But by Allah, they did not stop till they killed him. Hudhaifa said, "May Allah forgive you." (The sub-narrator, `Urwa, said, "By Allah, Hudhaifa continued asking Allah's Forgiveness for the killers of his father till he departed to Allah (i.e. died).")

`Aisha said that the Jews came to the Prophet and said, "As-Samu 'Alaikum" (death be on you). `Aisha said (to them), "(Death) be on you, and may Allah curse you and shower His wrath upon you!" The Prophet said, "Be calm, O `Aisha ! You should be kind and lenient, and beware of harshness and Fuhsh (i.e. bad words)." She said (to the Prophet), "Haven't you heard what they (Jews) have said?" He said, "Haven't you heard what I have said (to them)? I said the same to them, and my invocation against them will be accepted while theirs against me will be rejected (by Allah). "

`Abdullah bin Mas`ud said, "While Allah's Apostle was praying beside the Ka`ba, there were some Quraish people sitting in a gathering. One of them said, 'Don't you see this (who does deeds just to show off)? Who amongst you can go and bring the dung, blood and the Abdominal contents (intestines, etc.) of the slaughtered camels of the family of so and so and then wait till he prostrates and put that in between his shoulders?' The most unfortunate amongst them (`Uqba bin Abi Mu'ait) went (and brought them) and when Allah's Apostle prostrated, he put them between his shoulders. The Prophet remained in prostration and they laughed so much so that they fell on each other. A passerby went to Fatima, who was a young girl in those days. She came running and the Prophet was still in prostration. She removed them and cursed upon the Quraish on their faces. When Allah's Apostle completed his prayer, he said, 'O Allah! Take revenge on Quraish.' He said so thrice and added, 'O Allah! take revenge on `Amr bin Hisham, `Utba bin Rabi`a, Shaiba bin Rabi`a, Al-Walid bin `Utba, Umaiya bin Khalaf, `Uqba bin Abi Mu'ait and `Umar a bin Al-Walid." `Abdullah added, "By Allah! I saw all of them dead in the battle field on the day of Badr and they were dragged and thrown in the Qalib (a well) at Badr: Allah's Apostle then said, 'Allah's curse has descended upon the people of the Qalib (well).
