The word(s) "erred" appears 20 time(s) in 18 verse(s) in Quran in Muhammad Pickthal translation.

(11) And thy Lord is Best Aware of all who are in the heavens and the earth. And we preferred some of the prophets above others, and unto David We gave the Psalms.

(12) Verily we have honoured the Children of Adam. We carry them on the land and the sea, and have made provision of good things for them, and have preferred them above many of those whom We created with a marked preferment.

(13) And We verily gave knowledge unto David and Solomon, and they said: Praise be to Allah, Who hath preferred us above many of His believing slaves!

(14) And when thou saidst unto him on whom Allah hath conferred favour and thou hast conferred favour: Keep thy wife to thyself, and fear Allah. And thou didst hide in thy mind that which Allah was to bring to light, and thou didst fear mankind whereas Allah hath a better right that thou shouldst fear Him. So when Zeyd had performed that necessary formality (of divorce) from her, We gave her unto thee in marriage, so that (henceforth) there may be no sin for believers in respect of wives of their adopted sons, when the latter have performed the necessary formality (of release) from them. The commandment of Allah must be fulfilled.

(15) (And again of their falsehood): He hath preferred daughters to sons.

(16) And he said: Lo! I have preferred the good things (of the world) to the remembrance of my Lord; till they were taken out of sight behind the curtain.

(17) And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn.

(18) Unto Him is referred (all) knowledge of the Hour. And no fruits burst forth from their sheaths, and no female carrieth or bringeth forth but with His knowledge. And on the day when He calleth unto them: Where are now My partners? they will say: We confess unto Thee, not one of us is a witness (for them).
