The word(s) "err" appears 126 time(s) in 119 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) What! has then your Lord preferred to give you sons, and (for Himself) taken daughters from among the angels? Most surely you utter a grievous saying.

(52) And whoever is blind in this, he shall (also) be blind in the hereafter; and more erring from the way.

(53) And whomsoever Allah guides, he is the follower of the right way, and whomsoever He causes to err, you shall not find for him guardians besides Him; and We will gather them together on the day of resurrection on their faces, blind and dumb and deaf; their abode is hell; whenever it becomes allayed We will add to their burning.

(54) And you might see the sun when it rose, decline from their cave towards the right hand, and when it set, leave them behind on the left while they were in a wide space thereof. This is of the signs of Allah; whomsoever Allah guides, he is the rightly guided one, and whomsoever He causes to err, you shall not find for him any friend to lead (him) aright.

(55) How clearly shall they hear and how clearly shall they see on the day when they come to Us; but the unjust this day are in manifest error.

(56) Say: As for him who remains in error, the Beneficent Allah will surely prolong his length of days, until they see what they were threatened with, either the punishment or the hour; then they shall know who is in more evil plight and weaker in forces

(57) He said: The knowledge thereof is with my Lord in a book, my Lord errs not, nor does He forget;

(58) He said: Certainly you have been, (both) you and your fathers, in manifest error.

(59) They shall say: O our Lord! our adversity overcame us and we were an erring people:

(60) And the hell shall be made manifest to the erring ones,
