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

(241) And Allah puts forward (another) example of two men, one of them dumb, who has no power over anything (disbeliever), and he is a burden on his master; whichever way he directs him, he brings no good. Is such a man equal to one (believer in the Islamic Monotheism) who commands justice, and is himself on the Straight Path?

(242) They recognise the Grace of Allah, yet they deny it (by worshipping others besides Allah) and most of them are disbelievers (deny the Prophethood of Muhammad صلى الله عليه و سلم).

(243) And (remember) the Day when We shall raise up from each nation a witness (their Messenger), then, those who disbelieved will not be given leave (to put forward excuses), nor will they be allowed (to return to the world) to repent and ask for Allah's Forgiveness (of their sins).

(244) And when those who did wrong (the disbelievers) will see the torment, then it will not be lightened unto them, nor will they be given respite.

(245) Those who disbelieved and hinder (men) from the Path of Allah, for them We will add torment to the torment because they used to spread corruption [by disobeying Allah themselves, as well as ordering others (mankind) to do so].

(246) And be not like her who undoes the thread which she has spun, after it has become strong, by taking your oaths as a means of deception among yourselves, lest a nation should be more numerous than another nation. Allah only tests you by this [i.e who obeys Allah and fulfils Allah's Covenant and who disobeys Allah and breaks Allah's Covenant]. And on the Day of Resurrection, He will certainly make clear to you that wherein you used to differ [i.e. a believer confesses and believes in the Oneness of Allah and in the Prophethood of Prophet Muhammad صلى الله عليه و سلم which the disbeliever denies and that is their difference amongst them in the life of this world] .

(247) And when We change a Verse (of the Qur'an,) in place of another - and Allah knows best what He sends down - they (the disbelievers) say: "You (O Muhammad صلى الله عليه و سلم) are but a Muftari! (forger, liar)." Nay, but most of them know not.

(248) Whoever disbelieved in Allah after his belief, except him who is forced thereto and whose heart is at rest with Faith; but such as open their breasts to disbelief, on them is wrath from Allah, and theirs will be a great torment.

(249) That is because they loved and preferred the life of this world over that of the Hereafter. And Allah guides not the people who disbelieve.

(250) Verily, Ibrahim (Abraham) was an Ummah (a leader having all the good righteous qualities), or a nation, obedient to Allah, Hanif (i.e. to worship none but Allah), and he was not one of those who were Al-Mushrikun (polytheists, idolaters, disbelievers in the Oneness of Allah, and those who joined partners with Allah).
