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

(11) The chieftains of his people said: Lo! we see thee surely in plain error.

(12) He said: O my people! There is no error in me, but I am a messenger from the Lord of the Worlds.

(13) He said: Terror and wrath from your Lord have already fallen on you. Would ye wrangle with me over names which ye have named, ye and your fathers, for which no warrant from Allah hath been revealed? Then await (the consequence), lo! I (also) am of those awaiting (it).

(14) And when the terror fell on them they cried: O Moses! Pray for us unto thy Lord, because He hath a covenant with thee. If thou removest the terror from us we verily will trust thee and will let the Children of Israel go with thee.

(15) But when We did remove from them the terror for a term which they must reach, behold! they broke their covenant.

(16) I shall turn away from My revelations those who magnify themselves wrongfully in the earth, and if they see each token believe it not, and if they see the way of righteousness choose it nor for (their) way, and if they see the way of error choose if for (their) way. That is because they deny Our revelations and are used to disregard them.

(17) Lo! Those who chose the calf (for worship), terror from their Lord and humiliation will come upon them in the life of the world. Thus do We requite those who invent a lie.

(18) Their brethren plunge them further into error and cease not.

(19) Such then is Allah, your rightful Lord. After the Truth what is there saving error? How then are ye turned away!

(20) Deem not that Allah is unaware of what the wicked do. He but giveth them a respite till a day when eyes will stare (in terror),
