3:87Aal-i-Imraan

“Allah will curse them and those who curse will curse them.” He said: “The inhabitants of the earth.”

" The protection granted by Muslims is one and must be respected by the humblest of them. And he who broke the covenant made by a Muslim, there is a curse of Allah, of his angels, and of the whole people upon him, and neither an obligatory act nor a supererogatory act would be accepted from him as recompense on the Day of Resurrection."

" He who violated the covenant with a Muslim, there is upon him the curse of Allah, of angels and of all people. Neither an obligatory act nor a supererogatory act would be accepted from him as recompense on the Day of Resurrection; and in the hadith transmitted by two other narrators these words are not found:" He who claimed false paternity." And in the hadith transmitted by Waki' there is no mention of the Day of Resurrection.

He who took the freed slave as his ally without the consent of his previous master, there is upon him the curse of Allah and that of His angels and that of the whole mankind, and there will not be accepted from him his obligatory acts or supercrogatory acts on the Day of Resurrection. This hadith is narrated through the same chain of transmitters, but with a slight change of words.

"The one who consumes Riba, the one who pays it, and the one who writes it down, if they know that it is Riba; the woman who does tattoos and the woman who has that done for the purpose of beautification; the one who withholds Sadaqah (Zakah); and the one who reverts to the life of a Bedouin after having emigrated- they will (all) be cursed upon the tongue of Muhammad on the Day of Resurrection."
