The word(s) "unbeliever" appears 125 time(s) in 122 verse(s) in Quran in Muhammad Habib Shakir translation.

(101) Are the unbelievers of yours better than these, or is there an exemption for you in the scriptures?

(102) But whoever has not the means, let him fast for two months successively before they touch each other; then as for him who is not able, let him feed sixty needy ones; that is in order that you may have faith in Allah and His Apostle, and these are Allah's limits, and the unbelievers shall have a painful punishment.

(103) Surely those who act in opposition to Allah and His Apostle shall be laid down prostrate as those before them were laid down prostrate; and indeed We have revealed clear communications, and the unbelievers shall have an abasing chastisement.

(104) O you who believe! when believing women come to you flying, then examine them; Allah knows best their faith; then if you find them to be believing women, do not send them back to the unbelievers, neither are these (women) lawful for them, nor are those (men) lawful for them, and give them what they have spent; and no blame attaches to you in marrying them when you give them their dowries; and hold not to the ties of marriage of unbelieving women, and ask for what you have spent, and let them ask for what they have spent. That is Allah's judgment; He judges between you, and Allah is Knowing, Wise.

(105) And if anything (out of the dowries) of your wives has passed away from you to the unbelievers, then your turn comes, give to those whose wives have gone away the like of what they have spent, and be careful of (your duty to) Allah in Whom you believe.

(106) O you who believe! do not make friends with a people with whom Allah is wroth; indeed they despair of the hereafter as the unbelievers despair of those in tombs.

(107) They desire to put out the light of Allah with their mouths but Allah will perfect His light, though the unbelievers may be averse.

(108) He it is Who created you, but one of you is an unbeliever and another of you is a believer; and Allah sees what you do.

(109) O Prophet! strive hard against the unbelievers and the hypocrites, and be hard against them; and their abode is hell; and evil is the resort.

(110) Or who is it that will be a host for you to assist you besides the Beneficent Allah? The unbelievers are only in deception.
