The word(s) "believer" appears 350 time(s) in 314 verse(s) in Quran in Muhammad Pickthal translation.

(301) Upon the disbelievers, which none can repel,

(302) And Noah said: My Lord! Leave not one of the disbelievers in the land.

(303) Say (O Muhammad, unto the disbelievers): I know not whether that which ye are promised is nigh, or if my Lord hath set a distant term for it.

(304) Not of ease, for disbelievers.

(305) We have appointed only angels to be wardens of the Fire, and their number have We made to be a stumbling-block for those who disbelieve; that those to whom the Scripture hath been given may have certainty, and that believers may increase in faith; and that those to whom the Scripture hath been given and believers may not doubt; and that those in whose hearts there is disease, and disbelievers, may say: What meaneth Allah by this similitude? Thus Allah sendeth astray whom He will, and whom He will He guideth. None knoweth the hosts of thy Lord save Him. This is naught else than a Reminder unto mortals.

(306) Lo! We have prepared for disbelievers manacles and carcans and a raging fire.

(307) So submit patiently to thy Lord's command, and obey not of them any guilty one or disbeliever.

(308) Lo! We warn you of a doom at hand, a day whereon a man will look on that which his own hands have sent before, and the disbeliever will cry: "Would that I were dust!"

(309) Those are the disbelievers, the wicked.

(310) This day it is those who believe who have the laugh of disbelievers,
