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

(191) Then after them We sent Musa (Moses) and Harun (Aaron) to Fir'aun (Pharaoh) and his chiefs with Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.). But they behaved arrogantly and were Mujrimun (disbelievers, sinners, polytheists, criminals) folk.

(192) "And Allah will establish and make apparent the truth by His Words, however much the Mujrimun (criminals, disbelievers, polytheists, sinners) may hate it."

(193) "And (it is revealed to me): Direct your face (O Muhammad صلى الله عليه وسلم) entirely towards the religion Hanif (Islamic Monotheism, i.e. to worship none but Allah Alone), and never be one of the Mushrikun (those who ascribe partners to Allah, polytheists, idolaters, disbelievers in the Oneness of Allah, and those who worship others along with Allah).

(194) And He it is Who has created the heavens and the earth in six Days and His Throne was on the water, that He might try you, which of you is the best in deeds. But if you were to say to them: "You shall indeed be raised up after death," those who disbelieve would be sure to say, "This is nothing but obvious magic. "

(195) Can they (Muslims) who rely on a clear proof (the Qur'an) from their Lord, and whom a witness [Jibril (Gabriel عليه السلام)] from Him recites (follows) it (can they be equal with the disbelievers); and before it, came the Book of Musa (Moses), a guidance and a mercy, they believe therein, but those of the sects (Jews, Christians and all the other non-Muslim nations) that reject it (the Qur'an), the Fire will be their promised meeting-place. So be not in doubt about it (i.e. those who denied Prophet Muhammad صلى الله عليه و سلم and also denied all that which he brought from Allah. Surely, they will enter Hell). Verily, it is the truth from your Lord, but most of the mankind believe not.

(196) Those who hinder (others) from the Path of Allah (Islamic Monotheism), and seek a crookedness therein, while they are disbelievers in the Hereafter.

(197) The chiefs who disbelieved among his people said: "We see you but a man like ourselves, nor do we see any follow you but the meanest among us and they (too) followed you without thinking. And we do not see in you any merit above us, in fact we think you are liars."

(198) So it (the ship) sailed with them amidst waves like mountains, and Nuh (Noah) called out to his son, who had separated himself (apart): "O my son! Embark with us and be not with the disbelievers."

(199) "And O my people! Ask forgiveness of your Lord and then repent to Him, He will send you (from the sky) abundant rain, and add strength to your strength, so do not turn away as Mujrimun (criminals, disbelievers in the Oneness of Allah)."

(200) And they were pursued by a curse in this world and (so they will be) on the Day of Resurrection. No doubt! Verily, 'Ad disbelieved in their Lord. So away with 'Ad, the people of Hud.
