The word(s) "error" appears 54 time(s) in 53 verse(s) in Quran in Muhammad Pickthal translation.

(31) Nor canst thou lead the blind out of their error. Thou canst make none to hear, save those who believe Our revelations and who have surrendered.

(32) Lo! He Who hath given thee the Qur'an for a law will surely bring thee home again. Say: My Lord is Best Aware of him who bringeth guidance and him who is in error manifest.

(33) Nor canst thou guide the blind out of their error. Thou canst make none to hear save those who believe in Our revelations so that they surrender (unto Him).

(34) This is the Creation of Allah. Now show me that which those (ye worship) beside Him have created. Nay, but the wrong-doers are in error manifest!

(35) And it becometh not a believing man or a believing woman, when Allah and His messenger have decided an affair (for them), that they should (after that) claim any say in their affair; and whoso is rebellious to Allah and His messenger, he verily goeth astray in error manifest.

(36) Hath he invented a lie concerning Allah, or is there in him a madness? Nay, but those who disbelieve in the Hereafter are in torment and far error.

(37) Say: Who giveth you provision from the sky and the earth? Say: Allah, Lo! we or you assuredly are rightly guided or in error manifest.

(38) Then truly I should be in error manifest.

(39) And when it is said unto them: Spend of that wherewith Allah hath provided you, those who disbelieve say unto those who believe: Shall we feed those whom Allah, if He willed, would feed? Ye are in naught else than error manifest.

(40) Is he whose bosom Allah hath expanded for Al-Islam, so that he followeth a light from his Lord, (as he who disbelieveth)? Then woe unto those whose hearts are hardened against remembrance of Allah. Such are in plain error.
