The word(s) "believer" appears 651 time(s) in 556 verse(s) in Quran in Mohsin Khan translation.

(21) And their Prophet (Samuel عليه السلام) said to them: Verily! The sign of His kingdom is that there shall come to you At-Tabut (a wooden box), wherein is Sakinah (peace and reassurance) from your Lord and a remnant of that which Musa (Moses) and Harun (Aaron) left behind, carried by the angels. Verily, in this is a sign for you if you are indeed believers.

(22) O you who believe! Spend of that with which We have provided for you, before a Day comes when there will be no bargaining, nor friendship, nor intercession. And it is the disbelievers who are the Zalimun (wrong-doers).

(23) Have you not looked at him who disputed with Ibrahim (Abraham) about his Lord (Allah), because Allah had given him the kingdom? When Ibrahim (Abraham) said (to him): "My Lord (Allah) is He Who gives life and causes death." He said, "I give life and cause death." Ibrahim (Abraham) said, "Verily! Allah brings the sun from the east; then bring it you from the west." So the disbeliever was utterly defeated. And Allah guides not the people, who are Zalimun (wrong-doers).

(24) Allah will destroy Riba (usury) and will give increase for Sadaqat (deeds of charity, alms, etc.) And Allah likes not the disbelievers, sinners.

(25) O you who believe! Be afraid of Allah and give up what remains (due to you) from Riba (usury) (from now onward), if you are (really) believers.

(26) The Messenger (Muhammad صلى الله عليه وسلم) believes in what has been sent down to him from his Lord, and (so do) the believers. Each one believes in Allah, His Angels, His Books, and His Messengers. (They say), "We make no distinction between one another of His Messengers" - and they say, "We hear, and we obey. (We seek) Your Forgiveness, our Lord, and to You is the return (of all)."

(27) There has already been a sign for you (O Jews) in the two armies that met (in combat i.e. the battle of Badr). One was fighting in the Cause of Allah, and as for the other, (they) were disbelievers. They (the believers) saw them (the disbelievers) with their own eyes twice their number (although they were thrice their number). And Allah supports with His Victory whom He wills. Verily, in this is a lesson for those who understand. (See Verse 8:44). (Tafsir At-Tabari)

(28) Let not the believers take the disbelievers as Auliya (supporters, helpers) instead of the believers, and whoever does that will never be helped by Allah in any way, except if you indeed fear a danger from them. And Allah warns you against Himself (His punishment) , and to Allah is the final return.

(29) Say (O Muhammad صلى الله عليه وسلم): "Obey Allah and the Messenger (Muhammad صلى الله عليه وسلم)." But if they turn away, then Allah does not like the disbelievers .

(30) And they (disbelievers) plotted to kill 'Îsa [(Jesus) عليه السلام], and Allah plotted too. And Allah is the Best of those who plot.
