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.
