The word(s) "disbelievers" appears 347 time(s) in 327 verse(s) in Quran in Mohsin Khan translation.

(191) And if you were to ask them: "Who has created the heavens and the earth and subjected the sun and the moon?" they will surely reply: "Allah." How then are they deviating (as polytheists and disbelievers)?

(192) And who does more wrong than he who invents a lie against Allah or denies the truth (Muhammad صلى الله عليه وسلم and his doctrine of Islamic Monotheism and this Qur'an), when it comes to him? Is there not a dwelling in Hell for disbelievers (in the Oneness of Allah and in His Messenger Muhammad صلى الله عليه وسلم)?

(193) And on the Day when the Hour will be established, the Mujrimun (disbelievers, sinners, criminals, polytheists) will be plunged into destruction with (deep regrets, sorrows, and) despair.

(194) And on the Day when the Hour will be established - that Day shall (all men) be separated (i.e. the believers will be separated from the disbelievers).

(195) (And remain always) turning in repentance to Him (only), and be afraid and dutiful to Him; and perform As-Salat (Iqamat-as-Salat) and be not of Al-Mushrikun (the polytheists, idolaters, disbelievers in the Oneness of Allah).

(196) Say (O Muhammad صلى الله عليه وسلم): "Travel in the land and see what was the end of those before (you)! Most of them were Mushrikun (polytheists, idolaters, disbelievers in the Oneness of Allah)."

(197) That He may reward those who believe (in the Oneness of Allah - Islamic Monotheism), and do righteous good deeds, out of His Bounty. Verily, He likes not the disbelievers.

(198) And if We send a wind [which would spoil the green growth (tilth) brought up by the previous rain], and they see (their tilth) turn yellow - behold, they then (after their being glad,) would become unthankful (to their Lord Allah as) disbelievers. [Tafsir At-Tabari]

(199) So verily, you (O Muhammad صلى الله عليه وسلم) cannot make the dead to hear (i.e. the disbelievers), nor can you make the deaf to hear the call, when they show their backs and turn away.

(200) And on the Day that the Hour will be established, the Mujrimun (criminals, disbelievers, polytheists, sinners) will swear that they stayed not but an hour - thus were they ever deluded [away from the truth (i.e. they used to tell lies and take false oaths, and turn away from the truth) in this life of the world)]
