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

(561) They only are the true believers who believe in Allah and His messenger and, when they are with him on some common errand, go not away until they have asked leave of him. Lo! those who ask leave of thee, those are they who believe in Allah and His messenger. So, if they ask thy leave for some affair of theirs, give leave to whom thou wilt of them, and ask for them forgiveness of Allah. Lo! Allah is Forgiving, Merciful.

(562) Those who disbelieve say: This is naught but a lie that he hath invented, and other folk have helped him with it, so that they have produced a slander and a lie.

(563) The Sovereignty on that day will be the True (Sovereignty) belonging to the Beneficent One, and it will be a hard day for disbelievers.

(564) And those who disbelieve say: Why is the Qur'an not revealed unto him all at once? (It is revealed) thus that We may strengthen thy heart therewith; and We have arranged it in right order.

(565) So obey not the disbelievers, but strive against them herewith with a great endeavour.

(566) Yet they worship instead of Allah that which can neither benefit them nor hurt them. The disbeliever was ever a partisan against his Lord.

(567) Save him who repenteth and believeth and doth righteous work; as for such, Allah will change their evil deeds to good deeds. Allah is ever Forgiving, Merciful.

(568) Say (O Muhammad, unto the disbelievers): My Lord would not concern Himself with you but for your prayer. But now ye have denied (the Truth), therefor there will be judgment.

(569) It may be that thou tormentest thyself (O Muhammad) because they believe not.

(570) Lo! herein is indeed a portent; yet most of them are not believers.
