The word(s) "unbeliever" appears 125 time(s) in 122 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) And as for those in whose hearts is a disease, it adds uncleanness to their uncleanness and they die while they are unbelievers.

(52) What! is it a wonder to the people that We revealed to a man from among themselves, saying: Warn the people and give good news to those who believe that theirs is a footing of firmness with their Lord. The unbelievers say: This is most surely a manifest enchanter.

(53) And it moved on with them amid waves like mountains; and Nuh called out to his son, and he was aloof: O my son! embark with us and be not with the unbelievers.

(54) To Him is due the true prayer; and those whom they pray to besides Allah give them no answer, but (they are) like one who stretches forth his two hands towards water that it may reach his mouth, but it will not reach it; and the prayer of the unbelievers is only in error.

(55) A likeness of the garden which the righteous are promised; there now beneath it rivers, its food and shades are perpetual; this is the requital of those who guarded (against evil), and the requital of the unbelievers is the fire.

(56) And those before them did indeed make plans, but all planning is Allah's; He knows what every soul earns, and the unbelievers shall come to know for whom is the (better) issue of the abode.

(57) (Of) Allah, Whose is whatever is in the heavens and whatever Is in the earth; and woe to the unbelievers on account of the severe chastisement,

(58) Then on the resurrection day He will bring them to disgrace and say: Where are the associates you gave Me, for whose sake you became hostile? Those who are given the knowledge will say: Surely the disgrace and the evil are this day upon the unbelievers:

(59) It may be that your Lord will have mercy on you, and if you again return (to disobedience) We too will return (to punishment), and We have made hell a prison for the unbelievers.

(60) And We will bring forth hell, exposed to view, on that day before the unbelievers.
