The word(s) "disbelieve" appears 269 time(s) in 248 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) Surely those who disbelieve, it being alike to them whether you warn them, or do not warn them, will not believe.

(2) Surely Allah is not ashamed to set forth any parable-- (that of) a gnat or any thing above that; then as for those who believe, they know that it is the truth from their Lord, and as for those who disbelieve, they say: What is it that Allah means by this parable: He causes many to err by it and many He leads aright by it! but He does not cause to err by it (any) except the transgressors,

(3) And (as to) those who disbelieve in and reject My communications, they are the inmates of the fire, in it they shall abide.

(4) And when you said: O Musa! we cannot bear with one food, therefore pray Lord on our behalf to bring forth for us out of what the earth grows, of its herbs and its cucumbers and its garlic and its lentils and its onions. He said: Will you exchange that which is better for that which is worse? Enter a city, so you will have what you ask for. And abasement and humiliation were brought down upon them, and they became deserving of Allah's wrath; this was so because they disbelieved in the communications of Allah and killed the prophets unjustly; this was so because they disobeyed and exceeded the limits.

(5) Yet you it is who slay your people and turn a party from among you out of their homes, backing each other up against them unlawfully and exceeding the limits; and if they should come to you, as captives you would ransom them-- while their very turning out was unlawful for you. Do you then believe in a part of the Book and disbelieve in the other? What then is the re ward of such among you as do this but disgrace in the life of this world, and on the day of resurrection they shall be sent back to the most grievous chastisement, and Allah is not at all heedless of what you do.

(6) And when there came to them a Book from Allah verifying that which they have, and aforetime they used to pray for victory against those who disbelieve, but when there came to them (Prophet) that which they did not recognize, they disbelieved in him; so Allah's curse is on the unbelievers.

(7) And certainly We have revealed to you clear communications and none disbelieve in them except the transgressors.

(8) And they followed what the Shaitans chanted of sorcery in the reign of Sulaiman, and Sulaiman was not an unbeliever, but the Shaitans disbelieved, they taught men sorcery and that was sent down to the two angels at Babel, Harut and Marut, yet these two taught no man until they had said, "Surely we are only a trial, therefore do not be a disbeliever." Even then men learned from these two, magic by which they might cause a separation between a man and his wife; and they cannot hurt with it any one except with Allah's permission, and they learned what harmed them and did not profit them, and certainly they know that he who bought it should have no share of good in the hereafter and evil was the price for which they sold their souls; had they but known this.

(9) Those who disbelieve from among the followers of the Book do not like, nor do the polytheists, that the good should be sent down to you from your Lord, and Allah chooses especially whom He pleases for His mercy, and Allah is the Lord of mighty grace.

(10) Those to whom We have given the Book read it as it ought to be read. These believe in it; and whoever disbelieves in it, these it is that are the losers.
