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

(441) 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)."

(442) We created not the heavens and the earth and all that is between them except with truth, and for an appointed term. But those who disbelieve turn away from that whereof they are warned.

(443) And when Our Clear Verses are recited to them, the disbelievers say of the truth (this Qur'an) when it reaches them: "This is plain magic!"

(444) Say: "Tell me! If this (Qur'an) is from Allah and you deny it, and a witness from among the Children of Israel ('Abdullah bin Salam رضي الله عنه) testifies that [this Qur'an is from Allah (like the Taurat (Torah)], and he believed (embraced Islam) while you are too proud (to believe)." Verily, Allah guides not the people who are Zalimun (polytheists, disbelievers and wrong-doers).

(445) And those who disbelieve (the strong and wealthy) say of those who believe (the weak and poor): "Had it (Islamic Monotheism to which Muhammad صلى الله عليه وسلم is inviting mankind) been a good thing, they (the weak and poor) would not have preceded us thereto!" And when they have not let themselves be guided by it (this Qur'an), they say: "This is an ancient lie!"

(446) On the Day when those who disbelieve (in the Oneness of Allah - Islamic Monotheism) will be exposed to the Fire (it will be said): "You received your good things in the life of the world, and you took your pleasure therein. Now this Day you shall be recompensed with a torment of humiliation, because you were arrogant in the land without a right, and because you used to rebel against Allah's Command (disobey Allah).

(447) Destroying everything by the Command of its Lord! So they became such that nothing could be seen except their dwellings! Thus do We recompense the people who are Mujrimun (polytheists, disbelievers, sinners)!

(448) And on the Day when those who disbelieve will be exposed to the Fire (it will be said to them): "Is this not the truth?" They will say: "Yes, By our Lord!" He will say: "Then taste the torment, because you used to disbelieve!"

(449) Therefore be patient (O Muhammad صلى الله عليه وسلم) as did the Messengers of strong will and be in no haste about them (disbelievers). On the Day when they will see that (torment) with which they are promised (i.e. threatened, it will be) as if they had not stayed more than an hour in a single day. (O mankind! this Qur'an is sufficient as) a clear Message (or proclamation to save yourself from destruction). But shall any be destroyed except the people who are Al-Fasiqun (the rebellious against Allah's Command, the disobedient to Allah)?

(450) Those who disbelieve (in the Oneness of Allah, and in the Message of Prophet Muhammad صلى الله عليه وسلم), and hinder (men) from the Path of Allah (Islamic Monotheism), He will render their deeds vain.
