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

(41) They rejoice because of favour from Allah and kindness, and that Allah wasteth not the wage of the believers.

(42) It is only the devil who would make (men) fear his partisans. Fear them not; fear Me, if ye are true believers.

(43) The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom.

(44) Who hoard their wealth and enjoin avarice on others, and hide that which Allah hath bestowed upon them of His bounty. For disbelievers We prepare a shameful doom;

(45) O ye who believe! Obey Allah, and obey the messenger and those of you who are in authority; and if ye have a dispute concerning any matter, refer it to Allah and the messenger if ye are (in truth) believers in Allah and the Last Day. That is better and more seemly in the end.

(46) So fight (O Muhammad) in the way of Allah Thou art not taxed (with the responsibility for anyone) except thyself - and urge on the believers. Peradventure Allah will restrain the might of those who disbelieve. Allah is stronger in might and stronger in inflicting punishment.

(47) It is not for a believer to kill a believer unless (it be) by mistake. He who hath killed a believer by mistake must set free a believing slave, and pay the blood-money to the family of the slain, unless they remit it as a charity.

And if he cometh of a folk between whom and you there is a covenant, then the blood-money must be paid unto his folk and (also) a believing slave must be set free. And whoso hath not the wherewithal must fast two consecutive months. A penance from Allah. Allah is Knower, Wise.

(48) Whoso slayeth a believer of set purpose, his reward is hell for ever. Allah is wroth against him and He hath cursed him and prepared for him an awful doom.

(49) O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye do.

(50) Those of the believers who sit still, other than those who have a (disabling) hurt, are not on an equality with those who strive in the way of Allah with their wealth and lives. Allah hath conferred on those who strive with their wealth and lives a rank above the sedentary. Unto each Allah hath promised good, but He hath bestowed on those who strive a great reward above the sedentary;
