The word(s) "disbelieve" appears 428 time(s) in 384 verse(s) in Quran in Muhammad Pickthal translation.

(281) Lo! (on that day) those who disbelieve are informed by proclamation: Verily Allah's abhorrence is more terrible than your abhorrence one of another, when ye were called unto the faith but did refuse.

(282) (It is said unto them): This is (your plight) because, when Allah only was invoked, ye disbelieved, but when some partner was ascribed to Him ye were believing. But the command belongeth only to Allah, the Sublime, the Majestic.

(283) Therefor (O believers) pray unto Allah, making religion pure for Him (only), however much the disbelievers be averse -

(284) Have they not travelled in the land to see the nature of the consequence for those who disbelieved before them? They were mightier than these in power and (in the) traces (which they left behind them) in the earth. Yet Allah seized them for their sins, and they had no protector from Allah.

(285) That was because their messengers kept bringing them clear proofs (of Allah's Sovereignty) but they disbelieved; so Allah seized them. Lo! He is Strong, severe in punishment.

(286) And when he brought them the Truth from Our presence, they said: Slay the sons of those who believe with him, and spare their women. But the plot of disbelievers is in naught but error.

(287) Ye call me to disbelieve in Allah and ascribe unto Him as partners that whereof I have no knowledge, while I call you unto the Mighty, the Forgiver.

(288) They say: Came not your messengers unto you with clear proofs? They say: Yea, verily. They say: Then do ye pray, although the prayer of disbelievers is in vain.

(289) Beside Allah? They say: They have failed us; but we used not to pray to anything before. Thus doth Allah send astray the disbelievers (in His guidance).

(290) But their faith could not avail them when they saw Our doom. This is Allah's law which hath ever taken course for His bondmen. And then the disbelievers will be ruined.
