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

(11) O ye who believe! spend of that wherewith We have provided you ere a day come when there will be no trafficking, nor friendship, nor intercession. The disbelievers, they are the wrong-doers.

(12) Let not the believers take disbelievers for their friends in preference to believers. Whoso doeth that hath no connection with Allah unless (it be) that ye but guard yourselves against them, taking (as it were) security. Allah biddeth you beware (only) of Himself. Unto Allah is the journeying.

(13) Say: Obey Allah and the messenger. But if they turn away, lo! Allah loveth not the disbelievers (in His guidance).

(14) And they (the disbelievers) schemed, and Allah schemed (against them): and Allah is the best of schemers.

(15) O ye who believe! If ye obey a party of those who have received the Scripture they will make you disbelievers after your belief.

(16) And ward off (from yourselves) the Fire prepared for disbelievers.

(17) And that Allah may prove those who believe, and may blight the disbelievers.

(18) The forgiveness is not for those who do ill-deeds until, when death attendeth upon one of them, he saith: Lo! I repent now; nor yet for those who die while they are disbelievers. For such We have prepared a painful doom.

(19) Who hoard their wealth and enjoin avarice on others, and hide that which Allah hath bestowed upon them of His bounty. For disbelievers We prepare a shameful doom;

(20) And when ye go forth in the land, it is no sin for you to curtail (your) worship if ye fear that those who disbelieve may attack you. In truth the disbelievers are an open enemy to you.
