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

(381) It is not for the Prophet, and those who believe, to pray for the forgiveness of idolaters even though they may be near of kin (to them) after it hath become clear that they are people of hell-fire.

(382) O ye who believe! Be careful of your duty to Allah, and be with the truthful.

(383) It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs so stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good.

(384) And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.

(385) O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).

(386) And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor).

(387) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(388) There hath come unto you a messenger, (one) of yourselves, unto whom aught that ye are overburdened is grievous, full of concern for you, for the believers full of pity, merciful.

(389) Is it a wonder for mankind that We have inspired a man among them, saying: Warn mankind and bring unto those who believe the good tidings that they have a sure footing with their Lord? The disbelievers say: Lo! this is a mere wizard.

(390) Unto Him is the return of all of you; it is a promise of Allah in truth. Lo! He produceth creation, then reproduceth it, that He may reward those who believe and do good works with equity; while, as for those who disbelieve, theirs will be a boiling drink and painful doom because they disbelieved.
