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

(41) So go about in the land for four months and know that you cannot weaken Allah and that Allah will bring disgrace to the unbelievers.

(42) Then Allah sent down His tranquillity upon His Apostle and upon the believers, and sent down hosts which you did not see, and chastised those who disbelieved, and that is the reward of the unbelievers.

(43) They desire to put out the light of Allah with their mouths, and Allah will not consent save to perfect His light, though the unbelievers are averse.

(44) And among them there is he who says: Allow me and do not try me. Surely into trial have they already tumbled down, and most surely hell encompasses the unbelievers.

(45) Let not then their property and their children excite your admiration; Allah only wishes to chastise them with these in this world's life and (that) their souls may depart while they are unbelievers.

(46) Allah has promised the hypocritical men and the hypocritical women and the unbelievers the fire of hell to abide therein; it is enough for them; and Allah has cursed them and they shall have lasting punishment.

(47) O Prophet! strive hard against the unbelievers and the hypocrites and be unyielding to them; and their abode is hell, and evil is the destination.

(48) And let not their property and their children excite your admiration; Allah only wishes to chastise them with these in this world and (that) their souls may depart while they are unbelievers

(49) It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Apostle of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;

(50) O you who believe! fight those of the unbelievers who are near to you and let them find in you hardness; and know that Allah is with those who guard (against evil).
