Abdullah bin Umar reported the prophet صلی اللہ علیہ وسلم 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.

Narrated Saeed ibn al-Musayyab: While the Messenger of Allah صلی اللہ علیہ وسلم was sitting with some of his companions, a man reviled Abu Bakr and insulted him. But Abu Bakr remained silent. He insulted him twice, but Abu Bakr controlled himself. He insulted him thrice and Abu Bakr took revenge on him. Then the Messenger of Allah صلی اللہ علیہ وسلم got up when Abu Bakr took revenge. Abu Bakr said: Were you angry with me, Messenger of Allah? The Messenger of Allah صلی اللہ علیہ وسلم 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.

The tradition mentioned above has also been transmitted by Abu Hurairah through a different chain of narrators. This version has: A man was reviling Abu Bakr.

Narrated Aishah, Ummul Muminin: Ibn Awn said: I asked about the meaning of intisar (revenge) in the Quranic 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. Aishah). She said: The Mother of the Faithful said: The Messenger of Allah صلی اللہ علیہ وسلم 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 Aishah. She tried to prevent her but she did not stop. So he (the Prophet) said to Aishah: Abuse her. So she abused her and dominated her. Zaynab then went to Ali and said: Aishah 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 Kabah! 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 صلی اللہ علیہ وسلم and spoke to him about that.

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. Abu Hurairah said: By Him in Whose hand my soul is, he spoke a word by which this world and the next world of his were destroyed.

Narrated Abu Bakrah: The Prophet صلی اللہ علیہ وسلم 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.
