The word(s) "disbelievers" appears 153 time(s) in 144 verse(s) in Quran in Muhammad Pickthal translation.

(121) Nay, but they marvel that a warner of their own hath come unto them; and the disbelievers say: This is a strange thing:

(122) Hastening toward the summoner; the disbelievers say: This is a hard day.

(123) Are your disbelievers better than those, or have ye some immunity in the scriptures?

(124) And he who findeth not (the wherewithal), let him fast for two successive months before they touch one another; and for him who is unable to do so (the penance is) the feeding of sixty needy ones. This, that ye may put trust in Allah and His messenger. Such are the limits (imposed by Allah); and for disbelievers is a painful doom.

(125) Lo! those who oppose Allah and His messenger will be abased even as those before them were abased; and We have sent down clear tokens, and for disbelievers is a shameful doom

(126) O ye who believe! When believing women come unto you as fugitives, examine them. Allah is Best Aware of their faith. Then, if ye know them for true believers, send them not back unto the disbelievers. They are not lawful for them (the disbelievers), nor are they (the disbelievers) lawful for them. And give them (the disbelievers) that which they have spent (upon them). And it is no sin for you to marry such women when ye have given them their dues. And hold not to the ties of disbelieving women; and ask for (the return of) that which ye have spent; and let them (the disbelievers) ask for that which they have spent. That is the judgment of Allah. He judgeth between you. Allah is Knower, Wise.

(127) And if any of your wives have gone from you unto the disbelievers and afterward ye have your turn (of triumph), then give unto those whose wives have gone the like of that which they have spent, and keep your duty to Allah in Whom ye are believers.

(128) O ye who believe! Be not friendly with a folk with whom Allah is wroth, (a folk) who have despaired of the Hereafter as the disbelievers despair of those who are in the graves.

(129) Fain would they put out the light of Allah with their mouths, but Allah will perfect His light however much the disbelievers are averse.

(130) O Prophet! Strive against the disbelievers and the hypocrites, and be stern with them. Hell will be their home, a hapless journey's end.
