The Prophet (pbuh) said: When I was taken up to heaven I passed by people who had nails of copper and were scratching their faces and their breasts. I said: Who are these people, Gabriel? He replied: They are those who were given to back biting and who aspersed people's honour.

The Prophet (pbuh) said: O community of people, who believed by their tongue, and belief did not enter their hearts, do not back-bite Muslims, and do not search for their faults, for if anyone searches for their faults, Allah will search for his fault, and if Allah searches for the fault of anyone, He disgraces him in his house.

The Prophet (pbuh) said: If anyone eats once at the cost of a Muslim's honour, Allah will give him a like amount of Jahannam to eat; if anyone clothes himself with a garment at the cost of a Muslim's honour, Allah will clothe him with like amount of Jahannam; and if anyone puts himself in a position of reputation and show Allah will disgrace him with a place of reputation and show on the Day of Resurrection.

The Prophet (pbuh) said: If anyone guards a believer from a hypocrite, Allah will send an angel who will guard his flesh on the Day of Resurrection from the fire of Jahannam; but if anyone attacks a Muslim saying something by which he wishes to disgrace him, he will be restrained by Allah on the bridge over Jahannam till he is acquitted of what he said.

The Prophet (pbuh) said: No (Muslim) man will desert a man who is a Muslim in a place where his respect may be violated and his honour aspersed without Allah deserting him in a place here he wishes his help; and no (Muslim) man who will help a Muslim in a place where his honour may be aspersed and his respect violated without Allah helping him in a place where he wishes his help.

The Prophet (pbuh) said: When a ruler seeks to make imputations against the people, he corrupts them.

The Prophet (pbuh) said: He who sees something which should be kept hidden and conceals it will be like one who has brought to life a girl buried alive.

The Prophet (pbuh) said: Allah has revealed to me that you must be humble, so that no one oppresses another and boasts over another.

Ibn Awn said: I asked about the meaning of intisar (revenge) in the Qur'anic verse: "But indeed if any do help and defend themselves (intasara) after a wrong (done) to them, against them there is no cause of blame." Then Ali ibn Zayd ibn Jad'an told me on the authority of Umm Muhammad, the wife of his father. Ibn Awn said: It was believed that she used to go to the Mother of the Faithful (i.e. 'Aisha). She said: The Mother of the Faithful said: The Apostle of Allah (pbuh) came upon me while Zaynab, daughter of Jahsh, was with us. He began to do something with his hand. I signalled to him until I made him understand about her. So he stopped. Zaynab came on and began to abuse 'Aisha. She tried to prevent her but she did not stop. So he (the Prophet) said to 'Aisha: Abuse her. So she abused her and dominated her. Zaynab then went to Ali and said: 'Aisha abused you and did (such and such). Then Fatimah came (to the Prophet) and he said to her: She is the favourite of your father, by the Lord of the Ka'bah! She then returned and said to them: I said to him such and such, and he said to me such and such. Then Ali came to the Prophet (pbuh) and spoke to him about that.

The Prophet (pbuh) said: Make a mention of the virtues of your dead, and refrain from (mentioning) their evils.

The Prophet (pbuh) said: There is no sin more fitted to have punishment meted out by Allah to its perpetrator in advance in this world along with what He stores up for him in the next world than oppression and severing ties of relationship.

The Prophet (pbuh) said: Avoid envy, for envy devours good deeds just as fire devours fuel or (he said) "grass."

The Prophet (pbuh) said: Do not invoke Allah's curse, Allah's anger, or Hell.

A man cursed the wind. The narrator Muslim's version has: The wind snatched away a man's cloak during the time of the Prophet (pbuh) and he cursed it. The Prophet (pbuh) said: Do not curse it, for it is under command, and if anyone curses a thing undeservedly, the curse returns upon him.

The Prophet (pbuh) said: It is not allowable for a believer to keep from a believer for more than three days. If three days pass, he should meet him and give him a salutation, and if he replies to it they will both have shared in the reward; but if he does not reply he will bear his sin (according to Ahmad's version) and the one who gives the salutation will have come forth from the sin of keeping apart.
