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

(371) Let not their wealth nor their children please thee! Allah purposeth only to punish them thereby in the world, and that their souls shall pass away while they are disbelievers.

(372) And when a surah is revealed (which saith): believe in Allah and strive along with His messenger, the men of wealth among them still ask leave of thee and say: Suffer us to be with those who sit (at home).

(373) But the messenger and those who believe with him strive with their wealth and their lives. Such are they for whom are the good things. Such are they who are the successful.

(374) And those among the wandering Arabs who had an excuse came in order that permission might be granted them. And those who lied to Allah and His messenger sat at home. A painful doom will fall on those of them who disbelieve.

(375) They will make excuse to you (Muslims) when ye return unto them. Say: Make no excuse, for we shall not believe you. Allah hath told us tidings of you. Allah and His messenger will see your conduct, and then ye will be brought back unto Him Who knoweth the Invisible as well as the Visible, and He will tell you what ye used to do.

(376) And of the wandering Arabs there is he who believeth in Allah and the Last Day, and taketh that which he expendeth and also the prayers of the messenger as acceptable offerings in the sight of Allah. Lo! verily it is an acceptable offering for them. Allah will bring them into His mercy. Lo! Allah is Forgiving, Merciful.

(377) And say (unto them): Act! Allah will behold your actions, and (so will) His messenger and the believers, and ye will be brought back to the Knower of the Invisible and the Visible, and He will tell you what ye used to do.

(378) And as for those who chose a place of worship out of opposition and disbelief, and in order to cause dissent among the believers, and as an outpost for those who warred against Allah and His messenger aforetime, they will surely swear: We purposed naught save good. Allah beareth witness that they verily are liars.

(379) Lo! Allah hath bought from the believers their lives and their wealth because the Garden will be theirs: they shall fight in the way of Allah and shall slay and be slain. It is a promise which is binding on Him in the Torah and the Gospel and the Qur'an. Who fulfilleth His covenant better than Allah? Rejoice then in your bargain that ye have made, for that is the supreme triumph.

(380) (Triumphant) are those who turn repentant (to Allah), those who serve (Him), those who praise (Him), those who fast, those who bow down, those who fall prostrate (in worship), those who enjoin the right and who forbid the wrong and those who keep the limits (ordained) of Allah - And give glad tidings to believers!
