The word(s) "curse" appears 50 time(s) in 45 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And they say: Our hearts are covered. Nay, Allah has cursed them on account of their unbelief; so little it is that they believe.

(2) And when there came to them a Book from Allah verifying that which they have, and aforetime they used to pray for victory against those who disbelieve, but when there came to them (Prophet) that which they did not recognize, they disbelieved in him; so Allah's curse is on the unbelievers.

(3) Surely those who conceal the clear proofs and the guidance that We revealed after We made it clear in the Book for men, these it is whom Allah shall curse, and those who curse shall curse them (too).

(4) Surely those who disbelieve and die while they are disbelievers, these it is on whom is the curse of Allah and the angels and men all;

(5) So when she brought forth, she said: My Lord! Surely I have brought it forth a female-- and Allah knew best what she brought forth-- and the male is not like the female, and I have named it Marium, and I commend her and her offspring into Thy protection from the accursed Shaitan.

(6) But whoever disputes with you in this matter after what has come to you of knowledge, then say: Come let us call our sons and your sons and our women and your women and our near people and your near people, then let us be earnest in prayer, and pray for the curse of Allah on the liars.

(7) (As for) these, their reward is that upon them is the curse of Allah and the angels and of men, all together.

(8) Of those who are Jews (there are those who) alter words from their places and say: We have heard and we disobey and: Hear, may you not be made to hear! and: Raina, distorting (the word) with their tongues and taunting about religion; and if they had said (instead): We have heard and we obey, and hearken, and unzurna it would have been better for them and more upright; but Allah has cursed them on account of their unbelief, so they do not believe but a little.

(9) O you who have been given the Book! believe that which We have revealed, verifying what you have, before We alter faces then turn them on their backs, or curse them as We cursed the violaters of the Sabbath, and the command of Allah shall be executed.

(10) Those are they whom Allah has cursed, and whomever Allah curses you shall not find any helper for him.
