Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم said: Avoid envy, for envy devours good deeds just as fire devours fuel or (he said) "grass. "

Narrated Anas ibn Malik: Sahl ibn Abu Umamah said that he and his father (Abu Umamah) visited Anas ibn Malik at Madina during the time (rule) of Umar ibn Abdul Aziz when he (Anas ibn Malik) was the governor of Madina. 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 صلی اللہ علیہ وسلم . I did not make a mistake except in one thing that I forgot. He said: The Messenger of Allah صلی اللہ علیہ وسلم 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 صلی اللہ علیہ وسلم 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 bin Muhammad said: He is Rabah bin al-Walid who heard from him (nimran). He (Marwan bin Muhammad) said: Yahya bin Hussain was confused in it.

Narrated Samurah ibn Jundub: The Prophet صلی اللہ علیہ وسلم said: Do not invoke Allah's curse, Allah's anger, or Hell.

Abu al-Darda said: I heard the Messenger of Allah صلی اللہ علیہ وسلم say: Men given to cursing will not be witnesses or intercessors.

Narrated Abdullah ibn Abbas: 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 صلی اللہ علیہ وسلم and he cursed it. The Prophet صلی اللہ علیہ وسلم said: Do not curse it, for it is under command, and if anyone curses a thing undeservedly, the curse returns upon him.

Narrated Aishah, Ummul Muminin: Something of her was stolen, and she began to curse him (i. e. the thief). The Messenger of Allah صلی اللہ علیہ وسلم said to her: Do not lessen his sin.

Anas bin Malik reported the Messenger of Allah صلی اللہ علیہ وسلم as saying: Do not hate each other ; do not envy each other; do not desert each other; and be the servants of Allah as brethren. It is not allowable for a Muslim to keep apart from his brother for more than three days.

Abu Ayyub al-Ansari reported the Messenger of Allah صلی اللہ علیہ وسلم as saying: it is not allowable for a Muslim to keep apart from his brother for more than three days. When they meet, this turns away from him, and that turns away from him. The better of the two is the one who initiates in salutation.

Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم 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.
