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

(461) And if those who disbelieve fight against you, they certainly would have turned their backs; then they would have found neither a Wali (protector, guardian) nor a helper.

(462) 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.

(463) When those who disbelieve had put in their hearts pride and haughtiness - the pride and haughtiness of the time of ignorance, - then Allah sent down His Sakinah (calmness and tranquillity) upon His Messenger (صلى الله عليه وسلم) and upon the believers, and made them stick to the word of piety (i.e. none has the right to be worshipped but Allah); and they were well entitled to it and worthy of it. And Allah is the All-Knower of everything.

(464) Muhammad (صلى الله عليه وسلم) is the Messenger of Allah. And those who are with him are severe against disbelievers, and merciful among themselves. You see them bowing and falling down prostrate (in prayer), seeking Bounty from Allah and (His) Good Pleasure. The mark of them (i.e. of their Faith) is on their faces (foreheads) from the traces of prostration (during prayers). This is their description in the Taurat (Torah). But their description in the Injeel (Gospel) is like a (sown) seed which sends forth its shoot, then makes it strong, and becomes thick and it stands straight on its stem, delighting the sowers, that He may enrage the disbelievers with them. Allah has promised those among them who believe (i.e. all those who follow Islamic Monotheism, the religion of Prophet Muhammad صلى الله عليه وسلم till the Day of Resurrection) and do righteous good deeds, forgiveness and a mighty reward (i.e. Paradise).

(465) Nay, they wonder that there has come to them a warner (Muhammad صلى الله عليه وسلم) from among themselves. So the disbelievers say: "This is a strange thing!

(466) (Allah will say to the angels): "Both of you throw into Hell every stubborn disbeliever (in the Oneness of Allah, in His Messengers).

(467) They said: "We have been sent to a people who are Mujrimun (polytheists, sinners, criminals, disbelievers in Allah)

(468) Then woe to those who disbelieve (in Allah and His Oneness - Islamic Monotheism) from their Day which they have been promised (for their punishment).

(469) Or do they intend a plot (against you O Muhammad صلى الله عليه وسلم)? But those who disbelieve (in the Oneness of Allah - Islamic Monotheism) are themselves plotted against!

(470) Hastening towards the caller. The disbelievers will say: "This is a hard Day."
