The word(s) "curses" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) curses were pronounced on those among the Children of Israel who rejected Faith, by the tongue of David and of Jesus the son of Mary: because they disobeyed and persisted in excesses.

(2) He will say: "Enter ye in the company of the peoples who passed away before you - men and jinns, - into the Fire." Every time a new people enters, it curses its sister-people (that went before), until they follow each other, all into the Fire. Saith the last about the first: "Our Lord! it is these that misled us: so give them a double penalty in the Fire." He will say: "Doubled for all": but this ye do not understand.
