The word(s) "believers" appears 593 time(s) in 512 verse(s) in Quran in Mohsin Khan translation.

(231) And say: "The truth is from your Lord." Then whosoever wills, let him believe; and whosoever wills, let him disbelieve. Verily, We have prepared for the Zalimun (polytheists and wrong-doers.), a Fire whose walls will be surrounding them (disbelievers in the Oneness of Allah). And if they ask for help (relief, water), they will be granted water like boiling oil, that will scald their faces. Terrible is the drink, and an evil Murtafaq (dwelling, resting place.)!

(232) "And as for the boy, his parents were believers, and we feared lest he should oppress them by rebellion and disbelief.

(233) And on that Day We shall present Hell to the disbelievers, plain to view -

(234) Do then those who disbelieved think that they can take My slaves [i.e., the angels, Allah's Messengers, 'Îsa (Jesus), son of Maryam (Mary)] as Auliya' (lords, gods, protectors) besides Me? Verily, We have prepared Hell as an entertainment for the disbelievers (in the Oneness of Allah - Islamic Monotheism) .

(235) Then the sects differed [i.e. the Christians about 'Îsa (Jesus) عليه السلام], so woe unto the disbelievers [those who gave false witness by saying that 'Îsa (Jesus) is the son of Allah] from the Meeting of a great Day (i.e. the Day of Resurrection, when they will be thrown in the blazing Fire) .

(236) How clearly will they (polytheists and disbelievers in the Oneness of Allah) see and hear the Day when they will appear before Us! But the Zalimun (polytheists and wrong-doers) today are in plain error.

(237) And when Our Clear Verses are recited to them, those who disbelieve (the rich and strong among the pagans of Quraish who live a life of luxury) say to those who believe (the weak, poor companions of Prophet Muhammad صلى الله عليه وسلم who have a hard life): "Which of the two groups (i.e. believers or disbelievers) is best in (point of) position and as regards station (place of council for consultation)."

(238) See you not that We have sent the Shayatin (devils) against the disbelievers to push them to do evil.

(239) And We shall drive the Mujrimun (polytheists, sinners, criminals, disbelievers in the Oneness of Allah) to Hell, in a thirsty state (like a thirsty herd driven down to water).

(240) Verily, those who believe [in the Oneness of Allah and in His Messenger (Muhammad صلى الله عليه وسلم)] and work deeds of righteousness, the Most Gracious (Allah) will bestow love for them (in the hearts of the believers).
