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

(221) 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.

(222) 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."

(223) And Musa (Moses) said: "If you disbelieve, you and all on earth together, then verily Allah is Rich (Free of all needs), Owner of all Praise."

(224) Has not the news reached you, of those before you, the people of Nuh (Noah), and 'Ad, and Thamud? And those after them? None knows them but Allah. To them came their Messengers with clear proofs, but they put their hands in their mouths (biting them from anger) and said: "Verily, we disbelieve in that with which you have been sent, and we are really in grave doubt as to that to which you invite us (i.e. Islamic Monotheism)."

(225) 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).

(226) The parable of those who disbelieved in their Lord is that their works are as ashes, on which the wind blows furiously on a stormy day; they shall not be able to get aught of what they have earned. That is the straying, far away (from the Right Path).

(227) 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).

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

(229) 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].

(230) 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!
