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

(231) And announce unto the believers the good tidings that they will have great bounty from Allah.

(232) And incline not to the disbelievers and the hypocrites. Disregard their noxious talk, and put thy trust in Allah. Allah is sufficient as Trustee.

(233) O Prophet! Lo! We have made lawful unto thee thy wives unto whom thou hast paid their dowries, and those whom thy right hand possesseth of those whom Allah hath given thee as spoils of war, and the daughters of thine uncle on the father's side and the daughters of thine aunts on the father's side, and the daughters of thine uncle on the mother's side and the daughters of thine aunts on the mother's side who emigrated with thee, and a believing woman if she give herself unto the Prophet and the Prophet desire to ask her in marriage - a privilege for thee only, not for the (rest of) believers - We are Aware of that which We enjoined upon them concerning their wives and those whom their right hands possess - that thou mayst be free from blame, for Allah is ever Forgiving, Merciful.

(234) O Prophet! Tell thy wives and thy daughters and the women of the believers to draw their cloaks close round them (when they go abroad). That will be better, so that they may be recognised and not annoyed. Allah is ever Forgiving, Merciful.

(235) Lo! Allah hath cursed the disbelievers, and hath prepared for them a flaming fire,

(236) And Satan indeed found his calculation true concerning them, for they follow him, all save a group of true believers.

(237) And those who disbelieve say: We believe not in this Qur'an nor in that which was before it; but oh, if thou couldst see, when the wrong-doers are brought up before their Lord, how they cast the blame one to another; how those who were despised (in the earth) say unto those who were proud: But for you, we should have been believers.

(238) And We sent not unto any township a warner, but its pampered ones declared: Lo! we are disbelievers in that wherewith ye have been sent.

(239) They will say: Be Thou Glorified. Thou (alone) art our Guardian, not them! Nay, but they worshipped the jinn; most of them were believers in them.

(240) He it is Who hath made you regents in the earth; so he who disbelieveth, his disbelief be on his own head. Their disbelief increaseth for the disbelievers, in their Lord's sight, naught save abhorrence. Their disbelief increaseth for the disbelievers naught save loss.
