The word(s) "curse" appears 45 time(s) in 40 verse(s) in Quran in Saheeh International translation.

(1) And they said, "Our hearts are wrapped." But, [in fact], Allah has cursed them for their disbelief, so little is it that they believe.

(2) And when there came to them a Book from Allah confirming that which was with them - although before they used to pray for victory against those who disbelieved - but [then] when there came to them that which they recognized, they disbelieved in it; so the curse of Allah will be upon the disbelievers.

(3) Indeed, those who conceal what We sent down of clear proofs and guidance after We made it clear for the people in the Scripture - those are cursed by Allah and cursed by those who curse,

(4) Indeed, those who disbelieve and die while they are disbelievers - upon them will be the curse of Allah and of the angels and the people, all together,

(5) Then whoever argues with you about it after [this] knowledge has come to you - say, "Come, let us call our sons and your sons, our women and your women, ourselves and yourselves, then supplicate earnestly [together] and invoke the curse of Allah upon the liars [among us]."

(6) Those - their recompense will be that upon them is the curse of Allah and the angels and the people, all together,

(7) Among the Jews are those who distort words from their [proper] usages and say, "We hear and disobey" and "Hear but be not heard" and "Ra'ina," twisting their tongues and defaming the religion. And if they had said [instead], "We hear and obey" and "Wait for us [to understand]," it would have been better for them and more suitable. But Allah has cursed them for their disbelief, so they believe not, except for a few.

(8) O you who were given the Scripture, believe in what We have sent down [to Muhammad], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the decree of Allah accomplished.

(9) Those are the ones whom Allah has cursed; and he whom Allah curses - never will you find for him a helper.

(10) But whoever kills a believer intentionally - his recompense is Hell, wherein he will abide eternally, and Allah has become angry with him and has cursed him and has prepared for him a great punishment.
