The word(s) "believe" appears 1108 time(s) in 903 verse(s) in Quran in Muhammad Habib Shakir translation.

(871) And most surely it is a great grief to the unbelievers.

(872) The unbelievers-- there is none to avert it--

(873) But what is the matter with those who disbelieve that they hasten on around you,

(874) And Nuh said: My Lord! leave not upon the land any dweller from among the unbelievers:

(875) Guiding to the right way, so we believe in it, and we will not set up any one with our Lord:

(876) And that when we heard the guidance, we believed in it; so whoever believes in his Lord, he should neither fear loss nor being overtaken (by disgrace):

(877) How, then, will you guard yourselves, if you disbelieve, on the day which shall make children grey-headed?

(878) For the unbelievers, anything but easy.

(879) And We have not made the wardens of the fire others than angels, and We have not made their number but as a trial for those who disbelieve, that those who have been given the book may be certain and those who believe may increase in faith, and those who have been given the book and the believers may not doubt, and that those in whose hearts is a disease and the unbelievers may say: What does Allah mean by this parable? Thus does Allah make err whom He pleases, and He guides whom He pleases, and none knows the hosts of your Lord but He Himself; and this is naught but a reminder to the mortals.

(880) Surely We have prepared for the unbelievers chains and shackles and a burning fire.
