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

(211) Allah created the heavens and the earth with truth. Lo! therein is indeed a portent for believers.

(212) In like manner We have revealed unto thee the Scripture, and those unto whom We gave the Scripture aforetime will believe therein; and of these (also) there are some who believe therein. And none deny Our revelations save the disbelievers.

(213) They bid thee hasten on the doom, when lo! hell verily will encompass the disbelievers

(214) Who doeth greater wrong than he who inventeth a lie concerning Allah, or denieth the truth when it cometh unto him? Is not there a home in hell for disbelievers?

(215) Within ten years - Allah's is the command in the former case and in the latter - and in that day believers will rejoice

(216) Have they not pondered upon themselves? Allah created not the heavens and the earth, and that which is between them, save with truth and for a destined end. But truly many of mankind are disbelievers in the meeting with their Lord.

(217) Say (O Muhammad, to the disbelievers): Travel in the land, and see the nature of the consequence for those who were before you! Most of them were idolaters.

(218) That He may reward out of His bounty those who believe and do good works. Lo! He loveth not the disbelievers (in His guidance).

(219) Verily We sent before thee (Muhammad) messengers to their own folk. Then we took vengeance upon those who were guilty (in regard to them). To help believers is ever incumbent upon Us.

(220) And they say: When we are lost in the earth, how can we then be re-created? Nay but they are disbelievers in the meeting with their Lord.
