The word(s) "believer" appears 297 time(s) in 275 verse(s) in Quran in Muhammad Habib Shakir translation.

(71) These are they to whom We gave the book and the wisdom and the prophecy; therefore if these disbelieve in it We have already entrusted with it a people who are not disbelievers in it.

(72) Therefore eat of that on which Allah's name has been mentioned if you are believers in His communications.

(73) Is he who was dead then We raised him to life and made for him a light by which he walks among the people, like him whose likeness is that of one in utter darkness whence he cannot come forth? Thus what they did was made fair seeming to the unbelievers.

(74) O assembly of jinn and men! did there not come to you apostles from among you, relating to you My communications and warning you of the meeting of this day of yours? They shall say: We bear witness against ourselves; and this world's life deceived them, and they shall bear witness against their own souls that they were unbelievers.

(75) A Book revealed to you-- so let there be no straitness in your breast on account of it-- that you may warn thereby, and a reminder close to the believers.

(76) Say: Who has prohibited the embellishment of Allah which He has brought forth for His servants and the good provisions? Say: These are for the believers in the life of this world, purely (theirs) on the resurrection day; thus do We make the communications clear for a people who know.

(77) Who is then more unjust than he who forges a lie against Allah or rejects His communications? (As for) those, their portion of the Book shall reach them, until when Our apostles come to them causing them to die, they shall say: Where is that which you used to call upon besides Allah? They would say: They are gone away from us; and they shall bear witness against themselves that they were unbelievers

(78) Who hinder (people) from Allah's way and seek to make it crooked, and they are disbelievers in the hereafter.

(79) And the inmates of the fire shall call out to the dwellers of the garden, saying: Pour on us some water or of that which Allah has given you. They shall say: Surely Allah has prohibited them both to the unbelievers.

(80) So We delivered him and those with him by mercy from Us, and We cut off the last of those who rejected Our communications and were not believers.
