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

(101) But as for those in whose hearts is a disease (of doubt, disbelief and hypocrisy), it will add suspicion and doubt to their suspicion, disbelief and doubt; and they die while they are disbelievers.

(102) Is it a wonder for mankind that We have sent Our Revelation to a man from among themselves (i.e. Prophet Muhammad صلى الله عليه وسلم) (saying): "Warn mankind (of the coming torment in Hell), and give good news to those who believe (in the Oneness of Allah and in His Prophet Muhammad صلى الله عليه وسلم) that they shall have with their Lord the rewards of their good deeds?" (But) the disbelievers say: "This is indeed an evident sorcerer (i.e. Prophet Muhammad صلى الله عليه وسلم and the Qur'an)!

(103) And indeed, We destroyed generations before you when they did wrong, while their Messengers came to them with clear proofs, but they were not such as to believe! Thus do We requite the people who are Mujrimun (disbelievers, polytheists, sinners, criminals).

(104) So who does more wrong than he who forges a lie against Allah or denies His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.)? Surely, the Mujrimun (criminals, sinners, disbelievers and polytheists) will never be successful!

(105) Say: "Tell me, if His torment should come to you by night or by day, which portion thereof would the Mujrimun (disbelievers, polytheists, sinners, criminals) hasten on ?"

(106) Then after them We sent Musa (Moses) and Harun (Aaron) to Fir'aun (Pharaoh) and his chiefs with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). But they behaved arrogantly and were Mujrimun (disbelievers, sinners, polytheists, criminals) folk.

(107) "And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals, disbelievers, polytheists, sinners) may hate it."

(108) "And (it is revealed to me): Direct your face (O Muhammad صلى الله عليه وسلم) entirely towards the religion Hanif (Islamic Monotheism, i.e. to worship none but Allah Alone), and never be one of the Mushrikun (those who ascribe partners to Allah, polytheists, idolaters, disbelievers in the Oneness of Allah, and those who worship others along with Allah).

(109) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.

(110) Those who hinder (others) from the Path of Allah (Islamic Monotheism), and seek a crookedness therein, while they are disbelievers in the Hereafter.
