Narrated Ibn Mas`ud: Once Allah's Apostle divided and distributed (the war booty). An Ansar man said, "By Allah! Muhammad, by this distribution, did not intend to please Allah." So I came to Allah's Apostle and informed him about it whereupon his face became changed with anger and he said, "May Allah bestow His Mercy on Moses for he was hurt with more than this, yet he remained patient."

Narrated Abu Musa: The Prophet heard a man praising another man and he was exaggerating in his praise. The Prophet said (to him). "You have destroyed (or cut) the back of the man."

Narrated Abu Bakra: A man was mentioned before the Prophet and another man praised him greatly The Prophet said, "May Allah's Mercy be on you! You have cut the neck of your friend." The Prophet repeated this sentence many times and said, "If it is indispensable for anyone of you to praise someone, then he should say, 'I think that he is so-and-so," if he really thinks that he is such. Allah is the One Who will take his accounts (as He knows his reality) and no-one can sanctify anybody before Allah." (Wuhaib narrated from Khalid, "Woe to you," instead of "Allah's Mercy be on you.")

Sa'd bin Abi Waqqas (may Allah be pleased with him) said: I never heard the Prophet (peace and blessings of Allah be upon him) say about any person who walked on the earth that he is from the people of Paradise, except for 'Abdullah bin Salam (may Allah be pleased with him).

Narrated Salim: that his father said; "When Allah's Apostle mentioned wh at he mentioned about (the hanging of) the Izar (waist sheet), Abu Bakr said, "O Allah's Apostle! My Izar slackens on one side (without my intention)." The Prophet said, "You are not among those (who, out of pride) drag their Izars behind them."

And the statement of Allah the Exalted in Surah Yunus «إنما بغيكم على أنفسكم‏» : "Indeed, your rebellion and injustice will only harm your own selves." And the statement of Allah the Exalted in Surah Al-Hajj «ثم بغي عليه لينصرنه الله‏» : "Then he was wronged, so Allah will surely help him." And in this chapter, there is also mention of the evil of stirring up corruption, whether against a Muslim or a disbeliever.

Narrated `Aisha: The Prophet continued for such-and-such period imagining that he has slept (had sexual relations) with his wives, and in fact he did not. One day he said, to me, "O `Aisha! Allah has instructed me regarding a matter about which I had asked Him. There came to me two men, one of them sat near my feet and the other near my head. The one near my feet, asked the one near my head (pointing at me), 'What is wrong with this man? The latter replied, 'He is under the effect of magic.' The first one asked, 'Who had worked magic on him?' The other replied, 'Lubaid bin Asam.' The first one asked, 'What material (did he use)?' The other replied, 'The skin of the pollen of a male date tree with a comb and the hair stuck to it, kept under a stone in the well of Dharwan."' Then the Prophet went to that well and said, "This is the same well which was shown to me in the dream. The tops of its date-palm trees look like the heads of the devils, and its water looks like the Henna infusion." Then the Prophet ordered that those things be taken out. I said, "O Allah's Apostle! Won't you disclose (the magic object)?" The Prophet said, "Allah has cured me and I hate to circulate the evil among the people." `Aisha added, "(The magician) Lubaid bin Asam was a man from Bani Zuraiq, an ally of the Jews."

And the statement of Allah (in Surah Al-Falaq) «ومن شر حاسد إذا حسد‏» : "And from the evil of the envier, O Allah, when he envies."

Narrated Abu Huraira: The Prophet said, "Beware of suspicion, for suspicion is the worst of false tales; and do not look for the others' faults and do not spy, and do not be jealous of one another, and do not desert (cut your relation with) one another, and do not hate one another; and O Allah's worshipers! Be brothers (as Allah has ordered you!")

Narrated Anas bin Malik: Allah's Apostle said, "Do not hate one another, and do not be jealous of one another, and do not desert each other, and O, Allah's worshipers! Be brothers. Lo! It is not permissible for any Muslim to desert (not talk to) his brother (Muslim) for more than three days."
