The word(s) "disbelieved" appears 83 time(s) in 81 verse(s) in Quran in Mohsin Khan translation.

(71) And thus We have revealed to you (O Muhammad صلى الله عليه و سلم) a Qur'an in Arabic that you may warn the Mother of the Towns (Makkah) and all around it, and warn (them) of the Day of Assembling of which there is no doubt: when a party will be in Paradise (those who believed in Allah and followed what Allah's Messenger صلى الله عليه و سلم brought them) and a party in the blazing Fire (Hell) (those who disbelieved in Allah and followed not what Allah's Messenger صلى الله عليه و سلم brought them).

(72) But as for those who disbelieved (it will be said to them): "Were not Our Verses recited to you? But you were proud, and you were a people who were Mujrimun (polytheists, disbelievers, sinners, criminals)."

(73) They are the ones who disbelieved (in the Oneness of Allah - Islamic Monotheism) and hindered you from Al-Masjid-al-Haram (at Makkah) and detained the sacrificial animals from reaching their place of sacrifice. Had there not been believing men and believing women whom you did not know, that you may kill them and on whose account a sin would have been committed by you without (your) knowledge, that Allah might bring into His Mercy whom He wills - if they (the believers and the disbelievers) had been apart, We verily would have punished those of them who disbelieved with painful torment.

(74) So this Day no ransom shall be taken from you (hypocrites), nor of those who disbelieved, (in the Oneness of Allah - Islamic Monotheism). Your abode is the Fire. That is your maula (friend - proper place), and worst indeed is that destination.

(75) O you who believe! Take not My enemies and your enemies (i.e. disbelievers and polytheists) as friends, showing affection towards them, while they have disbelieved in what has come to you of the truth (i.e. Islamic Monotheism, this Qur'an, and Muhammad صلى الله عليه وسلم), and have driven out the Messenger (Muhammad صلى الله عليه وسلم) and yourselves (from your homeland) because you believe in Allah your Lord! If you have come forth to strive in My Cause and to seek My Good Pleasure, (then take not these disbelievers and polytheists as your friends). You show friendship to them in secret, while I am All-Aware of what you conceal and what you reveal. And whosoever of you (Muslims) does that, then indeed he has gone (far) astray from the Straight Path .

(76) O you who believe! Be you helpers (in the Cause) of Allah as said 'Îsa (Jesus), son of Maryam (Mary), to the Hawariyyun (the disciples): "Who are my helpers (in the Cause) of Allah?" The Hawariyyun (the disciples) said: "We are Allah's helpers" (i.e. we will strive in His Cause!). Then a group of the Children of Israel believed and a group disbelieved. So We gave power to those who believed against their enemies, and they became the victorious (uppermost).

(77) That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.

(78) Has not the news reached you of those who disbelieved aforetime? And so they tasted the evil result of their disbelief, and theirs will be a painful torment.

(79) That was because there came to them their Messengers with clear proofs (signs), but they said: "Shall mere men guide us?" So they disbelieved and turned away (from the truth). But Allah was not in need (of them). And Allah is Rich (Free of all needs), Worthy of all praise.

(80) But those who disbelieved (in the Oneness of Allah - Islamic Monotheism) and denied Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will be the dwellers of the Fire, to dwell therein forever. And worst indeed is that destination .
