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

(171) So let not their wealth nor their children amaze you (O Muhammad صلى الله عليه وسلم); in reality Allah's Plan is to punish them with these things in the life of this world, and that their souls shall depart (die) while they are disbelievers.

(172) Make no excuse; you disbelieved after you had believed. If We pardon some of you, We will punish others amongst you because they were Mujrimun (disbelievers, polytheists, sinners, criminals.).

(173) Allah has promised the hypocrites - men and women - and the disbelievers, the Fire of Hell; therein shall they abide. It will suffice them. Allah has cursed them and for them is the lasting torment.

(174) O Prophet (Muhammad صلى الله عليه وسلم)! Strive hard against the disbelievers and the hypocrites, and be harsh against them, their abode is Hell, - and worst indeed is that destination.

(175) They swear by Allah that they said nothing (bad), but really they said the word of disbelief, and they disbelieved after accepting Islam, and they resolved that (plot to murder Prophet Muhammad صلى الله عليه وسلم) which they were unable to carry out, and they could not find any cause to do so except that Allah and His Messenger had enriched them of His Bounty. If then they repent, it will be better for them, but if they turn away, Allah will punish them with a painful torment in this worldly life and in the Hereafter. And there is none for them on earth as a Wali (supporter, protector) or a helper.

(176) Whether you (O Muhammad صلى الله عليه وسلم) ask forgiveness for them (hypocrites) or ask not forgiveness for them - (and even) if you ask seventy times for their forgiveness - Allah will not forgive them because they have disbelieved in Allah and His Messenger (Muhammad صلى الله عليه وسلم). And Allah guides not those people who are Fasiqun (rebellious, disobedient to Allah).

(177) And never (O Muhammad صلى الله عليه وسلم) pray (funeral prayer) for any of them (hypocrites) who dies, nor stand at his grave. Certainly they disbelieved in Allah and His Messenger, and died while they were Fasiqun (rebellious, - disobedient to Allah and His Messenger صلى الله عليه وسلم).

(178) And let not their wealth or their children amaze you. Allah's Plan is to punish them with these things in this world, and that their souls shall depart (die) while they are disbelievers.

(179) And those who made excuses from the bedouins came (to you, O Prophet صلى الله عليه وسلم) asking your permission to exempt them (from the battle), and those who had lied to Allah and His Messenger sat at home (without asking the permission for it); a painful torment will seize those of them who disbelieve.

(180) It is not (proper) for the Prophet and those who believe to ask Allah's Forgiveness for the Mushrikun (polytheists, idolaters, pagans, disbelievers in the Oneness of Allah), even though they be of kin, after it has become clear to them that they are the dwellers of the Fire (because they died in a state of disbelief).
