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

(291) Or [the state of a disbeliever] is like the darkness in a vast deep sea, overwhelmed with waves topped by waves, topped by dark clouds, (layers of) darkness upon darkness: if a man stretches out his hand, he can hardly see it! And he for whom Allah has not appointed light, for him there is no light.

(292) They (hypocrites) say: "We have believed in Allah and in the Messenger (Muhammad صلى الله عليه وسلم), and we obey," then a party of them turn away thereafter, such are not believers.

(293) The only saying of the faithful believers, when they are called to Allah (His Words, the Qur'an) and His Messenger (صلى الله عليه وسلم), to judge between them, is that they say: "We hear and we obey." And such are the successful (who will live forever in Paradise).

(294) Allah has promised those among you who believe and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the land, as He granted it to those before them, and that He will grant them the authority to practise their religion which He has chosen for them (i.e. Islam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me. But whoever disbelieves after this, they are the Fasiqun (rebellious, disobedient to Allah).

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

(296) 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.

(297) 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)].

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

(299) 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).

(300) 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.
