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

(301) And who does more wrong than the one who invents a lie against Allah, while he is being invited to Islam? And Allah guides not the people who are Zalimun (polytheists, wrong-doers and disbelievers) folk.

(302) They intend to put out the Light of Allah (i.e. the Religion of Islam, this Qur'an, and the Prophet Muhammad صلى الله عليه وسلم) with their mouths. But Allah will bring His Light to perfection even though the disbelievers hate (it).

(303) He it is Who has sent His Messenger (Muhammad صلى الله عليه وسلم) with guidance and the religion of truth (Islamic Monotheism) to make it victorious over all (other) religions even though the Mushrikun (polytheists, pagans, idolaters, and disbelievers in the Oneness of Allah and in His Messenger Muhammad صلى الله عليه وسلم) hate (it).

(304) The likeness of those who were entrusted with the (obligation of the) Taurat (Torah) (i.e. to obey its commandments and to practise its laws), but who subsequently failed in those (obligations), is as the likeness of a donkey which carries huge burdens of books (but understands nothing from them). How bad is the example of people who deny the Ayat (proofs, evidence, verses, signs, revelations) of Allah. And Allah guides not the people who are Zalimun (polytheists, wrong-doers, disbelievers).

(305) But they will never long for it (death), because of what (deeds) their hands have sent before them! And Allah knows well the Zalimun (polytheists, wrong-doers, disbelievers).

(306) He it is Who created you, then some of you are disbelievers and some of you are believers. And Allah is All-Seer of what you do.

(307) The disbelievers pretend that they will never be resurrected (for the Account). Say (O Muhammad صلى الله عليه وسلم): Yes! By my Lord, you will certainly be resurrected, then you will be informed of (and recompensed for) what you did; and that is easy for Allah.

(308) (And remember) the Day when He will gather you (all) on the Day of Gathering, - that will be the Day of mutual loss and gain (i.e. loss for the disbelievers as they will enter the Hell-fire and gain for the believers as they will enter Paradise). And whosoever believes in Allah and performs righteous good deeds, He will expiate from him his sins, and will admit him to Gardens under which rivers flow (Paradise) to dwell therein forever; that will be the great success.

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

(310) And Allah has set forth an example for those who believe: the wife of Fir'aun (Pharaoh), when she said: "My Lord! Build for me a home with You in Paradise, and save me from Fir'aun (Pharaoh) and his work, and save me from the people who are Zalimun (polytheists, wrong-doers and disbelievers in Allah).
