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

(121) See they not that We gradually reduce the land (of the disbelievers, by giving it to the believers, in war victories) from its outlying borders. And Allah judges, there is none to put back His Judgement and He is Swift at reckoning.

(122) And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination).

(123) Allah to Whom belongs all that is in the heavens and all that is in the earth! And woe unto the disbelievers from a severe torment.

(124) 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."

(125) 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).

(126) And He gave you of all that you asked for, and if you count the Blessings of Allah, never will you be able to count them. Verily, man is indeed an extreme wrong-doer, a disbeliever (an extreme ingrate who denies Allah's Blessings by disbelief, and by worshipping others besides Allah, and by disobeying Allah and His Prophet Muhammad صلى الله عليه و سلم).

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

(128) 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].

(129) 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!

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