The word(s) "curse" appears 42 time(s) in 37 verse(s) in Quran in Muhammad Pickthal translation.

(21) A curse is made to follow them in the world and on the Day of Resurrection. Hapless is the gift (that will be) given (them).

(22) And those who break the covenant of Allah after ratifying it, and sever that which Allah hath commanded should be joined, and make mischief in the earth: theirs is the curse and theirs the ill abode.

(23) And lo! the curse shall be upon thee till the Day of Judgment.

(24) And (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety.

(25) And yet a fifth, invoking the curse of Allah on him if he is of those who lie.

(26) Lo! as for those who traduce virtuous, believing women (who are) careless, cursed are they in the world and the Hereafter. Theirs will be an awful doom

(27) And We made a curse to follow them in this world, and on the Day of Resurrection they will be among the hateful.

(28) He said: Ye have chosen only idols instead of Allah. The love between you is only in the life of the world. Then on the Day of Resurrection ye will deny each other and curse each other, and your abode will be the Fire, and ye will have no helpers.

(29) Lo! those who malign Allah and His messenger, Allah hath cursed them in the world and the Hereafter, and hath prepared for them the doom of the disdained.

(30) Accursed, they will be seized wherever found and slain with a (fierce) slaughter.
