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

(51) Then when you have finished the prayer, remember Allah standing and sitting and reclining; but when you are secure (from danger) keep up prayer; surely prayer is a timed ordinance for the believers.

(52) And whoever acts hostilely to the Apostle after that guidance has become manifest to him, and follows other than the way of the believers, We will turn him to that to which he has (himself) turned and make him enter hell; and it is an evil resort.

(53) And whoever does good deeds whether male or female and he (or she) is a believer-- these shall enter the garden, and they shall not be dealt with a jot unjustly.

(54) Those who take the unbelievers for guardians rather than believers. Do they seek honor from them? Then surely all honor is for Allah.

(55) And indeed He has revealed to you in the Book that when you hear Allah's communications disbelieved in and mocked at do not sit with them until they enter into some other discourse; surely then you would be like them; surely Allah will gather together the hypocrites and the unbelievers all in hell.

(56) Those who wait for (some misfortune to befall) you then If you have a victory from Allah they say: Were we not with you? And if there is a chance for the unbelievers, they say: Did we not acquire the mastery over you and defend you from the believers? So Allah shall Judge between you on the day of resurrection, and Allah will by no means give the unbelievers a way against the believers.

(57) O you who believe! do not take the unbelievers for friends rather than the believers; do you desire that you should give to Allah a manifest proof against yourselves?

(58) Except those who repent and amend and hold fast to Allah and are sincere in their religion to Allah, these are with the believers, and Allah will grant the believers a mighty reward.

(59) These it is that are truly unbelievers, and We have prepared for the unbelievers a disgraceful chastisement.

(60) And their taking usury though indeed they were forbidden it and their devouring the property of people falsely, and We have prepared for the unbelievers from among them a painful chastisement.
