Narrated Mu'awiyah: I heard the Messenger of Allah (ﷺ) say: If you search for the faults of the people, you will corrupt them, or will nearly corrupt them. AbudDarda' said: These are the words which Mu'awiyah himself from the Messenger of Allah (ﷺ), and Allah benefited him by them.

I then said to Uqbah ibn Amir: These neighbours of ours drink wine, and I tried to prevent them but they did not stop, and I am going to call the police about them. He said: Leave them. I again came to Uqbah ibn Amir and said: Our neighbours have refused to refrain from drinking wine, and I am going to call the police for them. He said: Woe to thee! Leave them alone. I heard the Messenger of Allah (ﷺ) say: he then mentioned the tradition to the same effect as recorded above on the authority of the narrator Muslim. Abu Dawud said: In this version Hashim b. al-Qasim said on the authority of Laith: Do not do it, but preach them and threaten them.

‘Abd Allah b. Umar reported the prophet (May peace be upon him) as saying : A Muslim is a Muslim’s brother: he does not wrong him or abandon him. If anyone cares for his brother’s need, Allah will care for his need ; if anyone removes a Muslim’s anxiety, Allah will remove from him, on account of it, one of the anxieties of the Day of resurrection ; and if anyone conceals a Muslim’s fault, Allah will conceal his fault on the Day of resurrection.

He insulted him twice, but AbuBakr controlled himself. He insulted him thrice and AbuBakr took revenge on him. Then the Messenger of Allah (ﷺ) got up when AbuBakr took revenge. AbuBakr said: Were you angry with me, Messenger of Allah? The Messenger of Allah (ﷺ) replied: An angel came down from Heaven and he was rejecting what he had said to you. When you took revenge, a devil came down. I was not going to sit when the devil came down.

Narrated Aisha, Ummul Mu'minin: 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 Messenger of Allah (ﷺ) 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 (ﷺ) and spoke to him about that.

Narrated AbuHurayrah: I heard the Messenger of Allah (ﷺ) say: There were two men among Banu Isra'il, who were striving for the same goal. One of them would commit sin and the other would strive to do his best in the world. The man who exerted himself in worship continued to see the other in sin. He would say: Refrain from it. One day he found him in sin and said to him: Refrain from it. He said: Leave me alone with my Lord. Have you been sent as a watchman over me? He said: I swear by Allah, Allah will not forgive you, nor will he admit you to Paradise. Then their souls were taken back (by Allah), and they met together with the Lord of the worlds. He (Allah) said to this man who had striven hard in worship; Had you knowledge about Me or had you power over that which I had in My hand? He said to the man who sinned: Go and enter Paradise by My mercy. He said about the other: Take him to Hell.

Narrated Anas ibn Malik: Sahl ibn AbuUmamah said that he and his father (AbuUmamah) visited Anas ibn Malik at Medina during the time (rule) of Umar ibn AbdulAziz when he (Anas ibn Malik) was the governor of Medina. He was praying a very short prayer as if it were the prayer of a traveller or near it. When he gave a greeting, my father said: May Allah have mercy on you! Tell me about this prayer: Is it obligatory or supererogatory? He said: It is obligatory; it is the prayer performed by the Messenger of Allah (ﷺ). I did not make a mistake except in one thing that I forgot. He said: The Messenger of Allah (ﷺ) used to say: Do not impose austerities on yourselves so that austerities will be imposed on you, for people have imposed austerities on themselves and Allah imposed austerities on them. Their survivors are to be found in cells and monasteries. (Then he quoted:) "Monasticism, they invented it; we did not prescribe it for them." Next day he went out in the morning and said: will you not go out for a ride, so that you may see something and take a lesson from it? He said: Yes. Then all of them rode away and reached a land whose inhabitants had perished, passed away and died. The roofs of the town had fallen in. He asked: Do you know this land? I said: Who acquainted me with it and its inhabitants? (Anas said:) This is the land of the people whom oppression and envy destroyed. Envy extinguishes the light of good deeds, and oppression confirms or falsifies it. The eye commits fornication, and the palm of the hand, the foot, body, tongue and private part of the body confirm it or deny it.

Abu al-Darda’ reported the Messenger of Allah (May peace be upon him) as saying : when a man cures anything, the curse goes up to heaven and the gates of heaven are locked against it. Then it comes down to the earth and its gates are locked against it. Then it goes right and left, and if it finds no place of entrance it returns to the thing which was cursed, and if it finds no place of entrance it returns to the thing which was cursed, and if it deserves what was said (it enters it), otherwise it returns to the one who uttered it. Abu Dawud said : Marwan b. Muhammad said: He is Rabah b. al-Walid who heard from him (nimran). He (Marwan b. Muhammad) said: Yahya b. Hussain was confused in it.
