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

(61) So they shall be thrown down into it, they and the erring ones,

(62) By Allah! we were certainly in manifest error,

(63) Nor can you be a guide to the blind out of their error; you cannot make to hear (any one) except those who believe in Our communications, so they submit.

(64) And on the day when the trumpet shall be blown, then those who are in the heavens and those who are in the earth shall be terrified except such as Allah please, and all shall come to him abased.

(65) Whoever brings good, he shall have better than it; and they shall be secure from terror on the day.

(66) And he was in the city, fearing, awaiting, when lo! he who had asked his assistance the day before was crying out to him for aid. Musa said to him: You are most surely one erring manifestly.

(67) But if they do not answer you, then know that they only follow their low desires; and who is more erring than he who follows his low desires without any guidance from Allah? Surely Allah does not guide the unjust people.

(68) And they say: If we follow the guidance with you, we shall be carried off from our country. What! have We not settled them in a safe, sacred territory to which fruits of every kind shall be drawn?-- a sustenance from Us; but most of them do not know.

(69) Those against whom the sentence has become confirmed will say: Our Lord! these are they whom we caused to err; we caused them to err as we ourselves did err; to Thee we declare ourselves to be clear (of them); they never served Us.

(70) Most surely He Who has made the Quran binding on you will bring you back to the destination. Say: My Lord knows best him who has brought the guidance and him who is in manifest error.
