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

(61) 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.

(62) 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.

(63) 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.

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

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

(66) 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,

(67) 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.

(68) 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.

(69) Say (O Muhammad, to the disbelievers): If there were other gods along with Him, as they say, then had they sought a way against the Lord of the Throne.

(70) Say: (It is) the truth from the Lord of you (all). Then whosoever will, let him believe, and whosoever will, let him disbelieve. Lo! We have prepared for disbelievers Fire. Its tent encloseth them. If they ask for showers, they will be showered with water like to molten lead which burneth the faces. Calamitous the drink and ill the resting-place!
