The word(s) "disbelieve" appears 631 time(s) in 561 verse(s) in Quran in Mohsin Khan translation.

(471) Are your disbelievers (O Quraish!) better than these [nations of Nuh (Noah), Lut (Lot), Salih, and the people of Fir'aun (Pharaoh) who were destroyed)? Or have you an immunity (against Our Torment) in the Divine Scriptures?

(472) Verily the Mujrimun (polytheists, disbelievers, sinners, criminals) are in error (in this world) and will burn (in the Hell-fire in the Hereafter).

(473) So on that Day no question will be asked of man or jinns as to his sin, [because they have already been known from their faces either white (dwellers of Paradise - true believers of Islamic Monotheism) or black (dwellers of Hell - polytheists; disbelievers, criminals)].

(474) Is it such a talk (this Qur'an) that you (disbelievers) deny?

(475) So this Day no ransom shall be taken from you (hypocrites), nor of those who disbelieved, (in the Oneness of Allah - Islamic Monotheism). Your abode is the Fire. That is your maula (friend - proper place), and worst indeed is that destination.

(476) And those who believe in (the Oneness of) Allah and His Messengers - they are the Siddiqun (i.e. those followers of the Prophets who were first and foremost to believe in them), and the martyrs with their Lord, they shall have their reward and their light. But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) and deny Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) - they shall be the dwellers of the blazing Fire.

(477) Know that the life of this world is only play and amusement, pomp and mutual boasting among you, and rivalry in respect of wealth and children. (It is) as the likeness of vegetation after rain, thereof the growth is pleasing to the tiller; afterwards it dries up and you see it turning yellow; then it becomes straw. But in the Hereafter (there is) a severe torment (for the disbelievers - evil-doers), and (there is) Forgiveness from Allah and (His) Good Pleasure (for the believers - good-doers). And the life of this world is only a deceiving enjoyment.

(478) And he who finds not (the money for freeing a slave) must fast two successive months before they both touch each other. And he who is unable to do so, should feed sixty Miskins (poor). That is in order that you may have perfect Faith in Allah and His Messenger. These are the limits set by Allah. And for disbelievers, there is a painful torment.

(479) Verily, those who oppose Allah and His Messenger (Muhammad صلى الله عليه وسلم) will be disgraced, as those before them (among the past nation) were disgraced. And We have sent down clear Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). And for the disbelievers is a disgracing torment.

(480) He it is Who drove out the disbelievers among the people of the Scripture (i.e. the Jews of the tribe of Banu An-Nadir) from their homes at the first gathering. You did not think that they would get out. And they thought that their fortresses would defend them from Allah! But Allah's (Torment) reached them from a place whereof they expected it not, and He cast terror into their hearts so that they destroyed their own dwellings with their own hands and the hands of the believers. Then take admonition, O you with eyes (to see).
