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

(121) And (remember) when your Lord proclaimed: "If you give thanks (by accepting Faith and worshipping none but Allah), I will give you more (of My Blessings); but if you are thankless (i.e. disbelievers), verily My punishment is indeed severe."

(122) And those who disbelieved, said to their Messengers: "Surely, we shall drive you out of our land, or you shall return to our religion." So their Lord revealed to them: "Truly, We shall destroy the Zalimun (polytheists, disbelievers and wrong-doers).

(123) And you will see the Mujrimun (criminals, disbelievers in the Oneness of Allah - Islamic Monotheism, polytheists) that Day Muqarranun (bound together) in fetters.

(124) How much would those who disbelieved wish that they had been Muslims [those who have submitted themselves to Allah's Will in Islam i.e. Islamic Monotheism - this will be on the Day of Resurrection when they will see the disbelievers going to Hell and the Muslims going to Paradise].

(125) We send not the angels down except with the truth (i.e. for torment), and in that case, they (the disbelievers) would have no respite!

(126) They (the angels) said: "We have been sent to a people who are Mujrimun (criminals, disbelievers, polytheists, sinners).

(127) Look not with your eyes ambitiously at what We have bestowed on certain classes of them (the disbelievers), nor grieve over them. And lower your wings for the believers (be courteous to the fellow-believers).

(128) Therefore proclaim openly (Allah's Message - Islamic Monotheism) that which you are commanded, and turn away from Al-Mushrikun (polytheists, idolaters, and disbelievers - See V.2:105).

(129) The Event (the Hour or the punishment of disbelievers and polytheists or the Islamic laws or commandments) ordained by Allah will come to pass, so seek not to hasten it. Glorified and Exalted be He above all that they associate as partners with Him.

(130) Then, on the Day of Resurrection, He will disgrace them and will say: "Where are My (so called) partners concerning whom you used to disagree and dispute (with the believers, by defying and disobeying Allah)?" Those who have been given the knowledge (about the Torment of Allah for the disbelievers) will say: "Verily! Disgrace and misery this Day are upon the disbelievers.
