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

(21) Let not the believers take the unbelievers for friends rather than believers; and whoever does this, he shall have nothing of (the guardianship of) Allah, but you should guard yourselves against them, guarding carefully; and Allah makes you cautious of (retribution from) Himself; and to Allah is the eventual coming.

(22) Say: Obey Allah and the Apostle; but if they turn back, then surely Allah does not love the unbelievers.

(23) And (make him) an apostle to the children of Israel: That I have come to you with a sign from your Lord, that I determine for you out of dust like the form of a bird, then I breathe into it and it becomes a bird with Allah's permission and I heal the blind and the leprous, and bring the dead to life with Allah's permission and I inform you of what you should eat and what you should store in your houses; most surely there is a sign in this for you, if you are believers.

(24) Most surely the nearest of people to Ibrahim are those who followed him and this Prophet and those who believe and Allah is the guardian of the believers.

(25) Surely, those who disbelieve and die while they are unbelievers, the earth full of gold shall not be accepted from one of them, though he should offer to ransom himself with it, these it is who shall have a painful chastisement, and they shall have no helpers.

(26) O you who believe! if you obey a party from among those who have been given the Book, they will turn you back as unbelievers after you have believed.

(27) You are the best of the nations raised up for (the benefit of) men; you enjoin what is right and forbid the wrong and believe in Allah; and if the followers of the Book had believed it would have been better for them; of them (some) are believers and most of them are transgressors.

(28) And when you did go forth early in the morning from your family to lodge the believers in encampments for war and Allah is Hearing, Knowing.

(29) When two parties from among you had determined that they should show cowardice, and Allah was the guardian of them both, and in Allah should the believers trust.

(30) When you said to the believers: Does it not suffice you that your Lord should assist you with three thousand of the angels sent down?
