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

(51) O you who believe! believe in Allah and His Apostle and the Book which He has revealed to His Apostle and the Book which He revealed before; and whoever disbelieves in Allah and His angels and His apostles and the last day, he indeed strays off into a remote error.

(52) Surely (as for) those who believe then disbelieve, again believe and again disbelieve, then increase in disbelief, Allah will not forgive them nor guide them in the (right) path.

(53) And indeed He has revealed to you in the Book that when you hear Allah's communications disbelieved in and mocked at do not sit with them until they enter into some other discourse; surely then you would be like them; surely Allah will gather together the hypocrites and the unbelievers all in hell.

(54) Surely those who disbelieve in Allah and His apostles and (those who) desire to make a distinction between Allah and His apostles and say: We believe in some and disbelieve in others, and desire to take a course between (this and) that.

(55) Surely (as for) those who disbelieve and hinder (men) from Allah's way, they indeed have strayed off into a remote

(56) Surely (as for) those who disbelieve and act unjustly Allah will not forgive them nor guide them to a path

(57) O people! surely the Apostle has come to you with the truth from your Lord, therefore believe, (it shall be) good for you and If you disbelieve, then surely whatever is in the heavens and the earth is Allah's; and Allah is Knowing, Wise.

(58) Forbidden to you is that which dies of itself, and blood, and flesh of swine, and that on which any other name than that of Allah has been invoked, and the strangled (animal) and that beaten to death, and that killed by a fall and that killed by being smitten with the horn, and that which wild beasts have eaten, except what you slaughter, and what is sacrificed on stones set up (for idols) and that you divide by the arrows; that is a transgression. This day have those who disbelieve despaired of your religion, so fear them not, and fear Me. This day have I perfected for you your religion and completed My favor on you and chosen for you Islam as a religion; but whoever is compelled by hunger, not inclining willfully to sin, then surely Allah is Forgiving, Merciful.

(59) And (as for) those who disbelieve and reject our communications, these are the companions of the name.

(60) And certainly Allah made a covenant with the children of Israel, and We raised up among them twelve chieftains; and Allah said: Surely I am with you; if you keep up prayer and pay the poor-rate and believe in My apostles and assist them and offer to Allah a goodly gift, I will most certainly cover your evil deeds, and I will most certainly cause you to enter into gardens beneath which rivers flow, but whoever disbelieves from among you after that, he indeed shall lose the right way.
