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

(271) Consider not that the disbelievers can escape in the land. Their abode shall be the Fire - and worst indeed is that destination.

(272) The true believers are only those, who believe in (the Oneness of) Allah and His Messenger (Muhammad صلى الله عليه وسلم): and when they are with him on some common matter, they go not away until they have asked his permission. Verily those who ask your permission, those are they who (really) believe in Allah and His Messenger. So if they ask your permission for some affairs of theirs, give permission to whom you will of them, and ask Allah for their forgiveness. Truly, Allah is Oft-Forgiving, Most Merciful.

(273) On the Day they will see the angels - no glad tidings will there be for the Mujrimun (criminals, disbelievers, polytheists, sinners) that day. And they (angels) will say: "All kinds of glad tidings are forbidden to you," [none will be allowed to enter Paradise except the one who said: La ilaha illallah, "(none has the right to be worshipped but Allah) and acted practically on its legal orders and obligations. See the footnote of V.2:193)].

(274) And We shall turn to whatever deeds they (disbelievers, polytheists, sinners) did, and We shall make such deeds as scattered floating particles of dust.

(275) The sovereignty on that Day will be the true (sovereignty), belonging to the Most Gracious (Allah), and it will be a hard Day for the disbelievers (those who disbelieve in the Oneness of Allah - Islamic Monotheism).

(276) Thus have We made for every Prophet an enemy among the Mujrimun (disbelievers, polytheists, criminals). But Sufficient is your Lord as a Guide and Helper.

(277) And indeed they have passed by the town [of Prophet Lut (Lot)] on which was rained the evil rain. Did they (disbelievers) not then see it (with their own eyes)? Nay! But they used not to expect any resurrection.

(278) So obey not the disbelievers, but strive against them (by preaching) with the utmost endeavour with it (the Qur'an).

(279) And they (disbelievers, polytheists) worship besides Allah that which can neither profit them nor harm them; and the disbeliever is ever a helper (of the Satan) against his Lord.

(280) Say (O Muhammad صلى الله عليه وسلم to the disbelievers): "My Lord pays attention to you only because of your invocation to Him. But now you have indeed denied (Him). So the torment will be yours for ever (inseparable, permanent punishment)."
