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

(11) And when there came to them (the Jews), a Book (this Qur'an) from Allah confirming what is with them [the Taurat (Torah) and the Injeel (Gospel)], although aforetime they had invoked Allah (for coming of Muhammad صلى الله عليه وسلم) in order to gain victory over those who disbelieved, then when there came to them that which they had recognised, they disbelieved in it. So let the Curse of Allah be on the disbelievers.

(12) How bad is that for which they have sold their ownselves, that they should disbelieve in that which Allah has revealed (the Qur'an), grudging that Allah should reveal of His Grace unto whom He wills of His slaves. So they have drawn on themselves wrath upon wrath. And for the disbelievers, there is disgracing torment.

(13) And when it is said to them (the Jews), "Believe in what Allah has sent down," they say, "We believe in what was sent down to us." And they disbelieve in that which came after it, while it is the truth confirming what is with them. Say (O Muhammad صلى الله عليه وسلم to them): "Why then have you killed the Prophets of Allah aforetime, if you indeed have been believers?"

(14) Whoever is an enemy to Allah, His Angels, His Messengers, Jibril (Gabriel) and Mika'il (Michael), then verily, Allah is an enemy to the disbelievers."

(15) And indeed We have sent down to you manifest Ayat (these Verses of the Qur'an which inform in detail about the news of the Jews and their secret intentions, etc.), and none disbelieve in them but Fasiqun (those who rebel against Allah's Command).

(16) They followed what the Shayatin (devils) gave out (falsely of the magic) in the lifetime of Sulaiman (Solomon). Sulaiman did not disbelieve, but the Shayatin (devils) disbelieved, teaching men magic and such things that came down at Babylon to the two angels, Harut and Marut, but neither of these two (angels) taught anyone (such things) till they had said, "We are only for trial, so disbelieve not (by learning this magic from us)." And from these (angels) people learn that by which they cause separation between man and his wife, but they could not thus harm anyone except by Allah's Leave. And they learn that which harms them and profits them not. And indeed they knew that the buyers of it (magic) would have no share in the Hereafter. And how bad indeed was that for which they sold their ownselves, if they but knew.

(17) O you who believe! Say not (to the Messenger صلى الله عليه وسلم) Ra'ina but say Unzurna (make us understand) and hear. And for the disbelievers there is a painful torment. (See Verse 4:46)

(18) Neither those who disbelieve among the people of the Scripture (Jews and Christians) nor Al-Mushrikun (the idolaters, polytheists, disbelievers in the Oneness of Allah, pagans, etc.) like that there should be sent down unto you any good from your Lord. But Allah chooses for His Mercy whom He wills. And Allah is the Owner of Great Bounty.

(19) Many of the people of the Scripture (Jews and Christians) wish that if they could turn you away as disbelievers after you have believed, out of envy from their ownselves, even after the truth (that Muhammad صلى الله عليه وسلم is Allah's Messenger) has become manifest unto them. But forgive and overlook, till Allah brings His Command. Verily, Allah is Able to do all things.

(20) Verily, We have sent you (O Muhammad صلى الله عليه وسلم) with the truth (Islam), a bringer of glad tidings (for those who believe in what you brought, that they will enter Paradise) and a warner (for those who disbelieve in what you brought, that they will enter the Hell-fire). And you will not be asked about the dwellers of the blazing Fire.
