The word(s) "believe" appears 1141 time(s) in 920 verse(s) in Quran in Muhammad Pickthal translation.

(11) Lo! Allah disdaineth not to coin the similitude even of a gnat. Those who believe know that it is the truth from their Lord; but those who disbelieve say: What doth Allah wish (to teach) by such a similitude? He misleadeth many thereby, and He guideth many thereby; and He misleadeth thereby only miscreants;

(12) How disbelieve ye in Allah when ye were dead and He gave life to you! Then He will give you death, then life again, and then unto Him ye will return.

(13) And when We said unto the angels: Prostrate yourselves before Adam, they fell prostrate, all save Iblis. He demurred through pride, and so became a disbeliever.

(14) But they who disbelieve, and deny Our revelations, such are rightful Peoples of the Fire. They will abide therein.

(15) And believe in that which I reveal, confirming that which ye possess already (of the Scripture), and be not first to disbelieve therein, and part not with My revelations for a trifling price, and keep your duty unto Me.

(16) And when ye said: O Moses! We will not believe in thee till we see Allah plainly; and even while ye gazed the lightning seized you.

(17) And when ye said: O Moses! We are weary of one kind of food; so call upon thy Lord for us that He bring forth for us of that which the earth groweth - of its herbs and its cucumbers and its corn and its lentils and its onions. He said: Would ye exchange that which is higher for that which is lower? Go down to settled country, thus ye shall get that which ye demand. And humiliation and wretchedness were stamped upon them and they were visited with wrath from Allah. That was because they disbelieved in Allah's revelations and slew the prophets wrongfully. That was for their disobedience and transgression.

(18) Lo! Those who believe (in that which is revealed unto thee, Muhammad), and those who are Jews, and Christians, and Sabaeans - whoever believeth in Allah and the Last Day and doeth right - surely their reward is with their Lord, and there shall no fear come upon them neither shall they grieve.

(19) And when they fall in with those who believe, they say: We believe. But when they go apart one with another they say: Prate ye to them of that which Allah hath disclosed to you that they may contend with you before your Lord concerning it? Have ye then no sense?

(20) And those who believe and do good works: such are rightful owners of the Garden. They will abide therein.
