The word(s) "disbelieve" appears 631 time(s) in 561 verse(s) in Quran in Mohsin Khan translation.

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

(352) 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."

(353) 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).

(354) Say: "On the Day of Al-Fath (Decision), no profit will it be to those who disbelieve if they (then) believe! Nor will they be granted a respite."

(355) 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.

(356) That He may ask the truthful (Allah's Messengers and His Prophets) about their truth (i.e. the conveyance of Allah's Message that which they were charged with). And He has prepared for the disbelievers a painful torment (Hell-fire).

(357) Among the believers are men who have been true to their covenant with Allah [i.e. they have gone out for Jihad (holy fighting), and showed not their backs to the disbelievers]; of them some have fulfilled their obligations (i.e. have been martyred); and some of them are still waiting, but they have never changed [i.e. they never proved treacherous to their covenant which they concluded with Allah] in the least.

(358) And Allah drove back those who disbelieved in their rage: they gained no advantage (booty). Allah sufficed for the believers in the fighting (by sending against the disbelievers a severe wind and troops of angels). And Allah is Ever All-Strong, All-Mighty.

(359) And those of the people of the Scripture who backed them (the disbelievers), Allah brought them down from their forts and cast terror into their hearts, (so that) a group (of them) you killed, and a group (of them) you made captives.

(360) And obey not the disbelievers and the hypocrites, and harm them not (in revenge for their harming you till you are ordered). And put your trust in Allah, and Sufficient is Allah as a Wakil (Trustee, or Disposer of affairs). [Tafsir Al-Qurtubi]
