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

(51) O Prophet! Strive against the disbelievers and the hypocrites! Be harsh with them. Their ultimate abode is hell, a hapless journey's end.

(52) Let not their wealth nor their children please thee! Allah purposeth only to punish them thereby in the world, and that their souls shall pass away while they are disbelievers.

(53) It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs so stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good.

(54) O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).

(55) But as for those in whose hearts is disease, it only addeth wickedness to their wickedness, and they die while they are disbelievers.

(56) Is it a wonder for mankind that We have inspired a man among them, saying: Warn mankind and bring unto those who believe the good tidings that they have a sure footing with their Lord? The disbelievers say: Lo! this is a mere wizard.

(57) Who debar (men) from the way of Allah and would have it crooked, and who are disbelievers in the Hereafter.

(58) And it sailed with them amid waves like mountains, and Noah cried unto his son - and he was standing aloof - O my son! Come ride with us, and be not with the disbelievers.

(59) He said: The food which ye are given (daily) shall not come unto you but I shall tell you the interpretation ere it cometh unto you. This is of that which my Lord hath taught me. Lo! I have forsaken the religion of folk who believe not in Allah and are disbelievers in the Hereafter.

(60) Unto Him is the real prayer. Those unto whom they pray beside Allah respond to them not at all, save as (is the response to) one who stretcheth forth his hands toward water (asking) that it may come unto his mouth, and it will never reach it. The prayer of disbelievers goeth (far) astray.
