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

(211) 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.

(212) 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]

(213) 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.

(214) 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)]

(215) And indeed We have set forth for mankind, in this Qur'an every kind of parable. But if you (O Muhammad صلى الله عليه وسلم) bring to them any sign or proof (as an evidence for the truth of your Prophethood), the disbelievers are sure to say (to the believers): "You follow nothing but falsehood, and magic."

(216) And if you only could see when the Mujrimun (criminals, disbelievers, polytheists, sinners) shall hang their heads before their Lord (saying): "Our Lord! We have now seen and heard, so send us back (to the world), that we will do righteous good deeds. Verily! We now believe with certainty."

(217) Is then he who is a believer like him who is a Fasiq (disbeliever and disobedient to Allah)? Not equal are they.

(218) And as for those who are Fasiqun (disbelievers and disobedient to Allah), their abode will be the Fire, every time they wish to get away therefrom, they will be put back thereto, and it will be said to them: "Taste you the torment of the Fire which you used to deny."

(219) And who does more wrong than he who is reminded of the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord, then turns aside therefrom? Verily, We shall exact retribution from the Mujrimun (criminals, disbelievers, polytheists, sinners).

(220) O Prophet (Muhammad صلى الله عليه وسلم)! Keep your duty to Allah, and obey not the disbelievers and the hypocrites (i.e., do not follow their advice). Verily, Allah is Ever All-Knower, All-Wise.
