I heard `Urwa bin Az-Zubair talking to `Umar bin `Abdul `Aziz during the latter's Governorship (at Medina), he said, "Al-Mughira bin Shu`ba delayed the `Asr prayer when he was the ruler of Al-Kufa. On that, Abu Mas`ud. `Uqba bin `Amr Al-Ansari, the grand-father of Zaid bin Hasan, who was one of the Badr warriors, came in and said, (to Al-Mughira), 'You know that Gabriel came down and offered the prayer and Allah's Apostle prayed five prescribed prayers, and Gabriel said (to the Prophet ), "I have been ordered to do so (i.e. offer these five prayers at these fixed stated hours of the day).

Allah's Apostle pointed with his hand towards Yemen and said, "(True) Belief is Yemenite, towards here (i.e. the Yemenite, had True Belief and embraced Islam readily). Certainly sternness and mercilessness are the qualities of those who are loud and at the base of the tails of camels, where the two horns of Satan will appear. Such qualities belong to the tribes of Rabi`a and Mudar."

While Allah's Apostle was prostrating (as stated below).

Narrated `Abdullah bin Mas`ud:

Once the Prophet was offering prayers at the Ka`ba. Abu Jahl was sitting with some of his companions. One of them said to the others, "Who amongst you will bring the Abdominal contents (intestines, etc.) of a camel of Bani so and so and put it on the back of Muhammad, when he prostrates?" The most unfortunate of them got up and brought it. He waited till the Prophet prostrated and then placed it on his back between his shoulders. I was watching but could not do any thing. I wish I had some people with me to hold out against them. They started laughing and falling on one another. Allah's Apostle was in prostration and he did not lift his head up till Fatima (Prophet's daughter) came and threw that (camel's Abdominal contents) away from his back. He raised his head and said thrice, "O Allah! Punish Quraish." So it was hard for Abu Jahl and his companions when the Prophet invoked Allah against them as they had a conviction that the prayers and invocations were accepted in this city (Mecca). The Prophet said, "O Allah! Punish Abu Jahl, `Utba bin Rabi`a, Shaiba bin Rabi`a, Al-Walid bin `Utba, Umaiya bin Khalaf, and `Uqba bin Al Mu'it [??] (and he mentioned the seventh whose name I cannot recall). By Allah in Whose Hands my life is, I saw the dead bodies of those persons who were counted by Allah's Apostle in the Qalib (one of the wells) of Badr.

The Prophet said, "One of the sayings of the prophets which the people have got, is. 'If you do not feel ashamed, then do whatever you like."

Ibrahim said: Ad-Dahhak ibn Qays intended to appoint Masruq as governor. Thereupon Umarah ibn Uqbah said to him: Are you appointing a man from the remnants of the murderers of Uthman? Masruq said to him: Ibn Mas'ud narrated to us, and he was trustworthy in respect of traditions, that when the Prophet (saws) intended to kill your father, he said: Who will look after my children? He replied: Fire. I also like for you what the Messenger of Allah (saws) liked for you.
