The word(s) "disbeliever" appears 160 time(s) in 151 verse(s) in Quran in Muhammad Pickthal translation.

(61) 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.

(62) 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.

(63) Thus We send thee (O Muhammad) unto a nation, before whom other nations have passed away, that thou mayst recite unto them that which We have inspired in thee, while they are disbelievers in the Beneficent. Say: He is my Lord; there is no Allah save Him. In Him do I put my trust and unto Him is my recourse.

(64) A similitude of the Garden which is promised unto those who keep their duty (to Allah): Underneath it rivers flow; its food is everlasting, and its shade; this is the reward of those who keep their duty, while the reward of disbelievers is the Fire.

(65) Those who were before them plotted; but all plotting is Allah's. He knoweth that which each soul earneth. The disbelievers will come to know for whom will be the sequel of the (heavenly) Home.

(66) Allah, unto Whom belongeth whatsoever is in the heavens and whatsoever is in the earth. and woe unto the disbelievers from an awful doom;

(67) We send not down the angels save with the Fact, and in that case (the disbelievers) would not be tolerated.

(68) Then on the Day of Resurrection He will disgrace them and will say: Where are My partners, for whose sake ye opposed (My guidance)? Those who have been given knowledge will say: Disgrace this day and evil are upon the disbelievers,

(69) And (bethink you of) the day when we raise up of every nation a witness, then there is no leave for disbelievers, nor are they allowed to make amends.

(70) It may be that your Lord will have mercy on you, but if ye repeat (the crime) We shall repeat (the punishment), and We have appointed hell a dungeon for the disbelievers.
