The word(s) "disbeliever" appears 377 time(s) in 355 verse(s) in Quran in Mohsin Khan translation.

(151) And the Book (one's Record) will be placed (in the right hand for a believer in the Oneness of Allah, and in the left hand for a disbeliever in the Oneness of Allah), and you will see the Mujrimun (criminals, polytheists, sinners), fearful of that which is (recorded) therein. They will say: "Woe to us! What sort of Book is this that leaves neither a small thing nor a big thing, but has recorded it with numbers!" And they will find all that they did, placed before them, and your Lord treats no one with injustice.

(152) He said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with a terrible torment (Hell).

(153) And on that Day We shall present Hell to the disbelievers, plain to view -

(154) Do then those who disbelieved think that they can take My slaves [i.e., the angels, Allah's Messengers, 'Îsa (Jesus), son of Maryam (Mary)] as Auliya' (lords, gods, protectors) besides Me? Verily, We have prepared Hell as an entertainment for the disbelievers (in the Oneness of Allah - Islamic Monotheism) .

(155) Then the sects differed [i.e. the Christians about 'Îsa (Jesus) عليه السلام], so woe unto the disbelievers [those who gave false witness by saying that 'Îsa (Jesus) is the son of Allah] from the Meeting of a great Day (i.e. the Day of Resurrection, when they will be thrown in the blazing Fire) .

(156) How clearly will they (polytheists and disbelievers in the Oneness of Allah) see and hear the Day when they will appear before Us! But the Zalimun (polytheists and wrong-doers) today are in plain error.

(157) And man (the disbeliever) says: "When I am dead, shall I then be raised up alive?"

(158) And when Our Clear Verses are recited to them, those who disbelieve (the rich and strong among the pagans of Quraish who live a life of luxury) say to those who believe (the weak, poor companions of Prophet Muhammad صلى الله عليه وسلم who have a hard life): "Which of the two groups (i.e. believers or disbelievers) is best in (point of) position and as regards station (place of council for consultation)."

(159) See you not that We have sent the Shayatin (devils) against the disbelievers to push them to do evil.

(160) And We shall drive the Mujrimun (polytheists, sinners, criminals, disbelievers in the Oneness of Allah) to Hell, in a thirsty state (like a thirsty herd driven down to water).
