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

(481) Have you (O Muhammad صلى الله عليه وسلم) not observed the hypocrites who say to their friends among the people of the Scripture who disbelieve: "(By Allah) If you are expelled, we (too) indeed will go out with you, and we shall never obey any one against you; and if you are attacked (in fight), we shall indeed help you." But Allah is Witness that they verily are liars.

(482) (Their allies deceived them) like Shaitan (Satan), when he says to man: "disbelieve in Allah." But when (man) disbelieves in Allah, Shaitan (Satan) says: "I am free of you, I fear Allah, the Lord of the 'Alamin (mankind, jinn and all that exists)!"

(483) So the end of both will be that they will be in the Fire, abiding therein. Such is the recompense of the Zalimun (i.e. polytheists, wrong-doers, disbelievers in Allah and in His Oneness).

(484) 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 .

(485) Should they gain the upper hand over you, they would behave to you as enemies, and stretch forth their hands and their tongues against you with evil, and they desire that you should disbelieve.

(486) "Our Lord! Make us not a trial for the disbelievers, and forgive us, Our Lord! Verily, You, only You, are the All-Mighty, the All-Wise."

(487) O you who believe! When believing women come to you as emigrants, examine them; Allah knows best as to their Faith, then if you ascertain that they are true believers send them not back to the disbelievers. They are not lawful (wives) for the disbelievers nor are the disbelievers lawful (husbands) for them. But give them (the disbelievers) that (amount of money) which they have spent [as their Mahr] to them. And there will be no sin on you to marry them if you have paid their Mahr to them. Likewise hold not the disbelieving women as wives, and ask for (the return of) that which you have spent (as Mahr ) and let them (the disbelievers) ask back for that which they have spent. That is the Judgement of Allah, He judges between you. And Allah is All-Knowing, All-Wise.

(488) And if any of your wives have gone from you to the disbelievers, (as apostates and you asked them to return back your Mahr but they refused) - then you went out for a Ghazwah (military expedition) (against them and) gained booty; then pay from that booty to those whose wives have gone, the equivalent of what they had spent (on their Mahr ). And fear Allah in Whom you believe.

(489) O you who believe! Take not as friends the people who incurred the Wrath of Allah (i.e. the Jews). Surely, they have despaired of (receiving any good in) the Hereafter, just as the disbelievers have despaired of those (buried) in graves (that they will not be resurrected on the Day of Resurrection).

(490) And who does more wrong than the one who invents a lie against Allah, while he is being invited to Islam? And Allah guides not the people who are Zalimun (polytheists, wrong-doers and disbelievers) folk.
