The word(s) "earn" appears 82 time(s) in 75 verse(s) in Quran in Abdullah Yusuf Ali translation.

(61) That is (the Bounty) whereof Allah gives Glad Tidings to His Servants who believe and do righteous deeds. Say: "No reward do I ask of you for this except the love of those near of kin." And if any one earns any good, We shall give him an increase of good in respect thereof: for Allah is Oft-Forgiving, Most Ready to appreciate (service).

(62) Or He can cause them to perish because of the (evil) which (the men) have earned; but much doth He forgive.

(63) We have made it a Qur'an in Arabic, that ye may be able to understand (and learn wisdom).

(64) And when he learns something of Our Signs, he takes them in jest: for such there will be a humiliating Penalty.

(65) In front of them is Hell: and of no profit to them is anything they may have earned, nor any protectors they may have taken to themselves besides Allah: for them is a tremendous Penalty.

(66) Tell those who believe, to forgive those who do not look forward to the Days of Allah: It is for Him to recompense (for good or ill) each People according to what they have earned.

(67) Allah created the heavens and the earth for just ends, and in order that each soul may find the recompense of what it has earned, and none of them be wronged.

(68) Do they not then earnestly seek to understand the Qur'an, or are their hearts locked up by them?

(69) Behold, two (guardian angels) appointed to learn (his doings) learn (and noted them), one sitting on the right and one on the left.

(70) Verily in this is a Message for any that has a heart and understanding or who gives ear and earnestly witnesses (the truth).
