The word(s) "earn" appears 87 time(s) in 77 verse(s) in Quran in Mohsin Khan translation.

(61) This Day shall every person be recompensed for what he earned. This Day no injustice (shall be done to anybody). Truly, Allah is Swift in reckoning.

(62) Have they not travelled through the earth and seen what was the end of those before them? They were more in number than them and mightier in strength, and in the traces (they have left behind them) in the land; yet all that they used to earn availed them not.

(63) And as for Thamud, We showed and made clear to them the Path of Truth (Islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance; so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them because of what they used to earn.

(64) You will see (on the Day of Resurrection), the Zalimun (polytheists and wrong-doers) fearful of that which they have earned, and it (Allah's Torment) will surely befall them. But those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous deeds (will be) in the flowering meadows of the Gardens (Paradise). They shall have whatsoever they desire with their Lord. That is the supreme Grace, (Paradise).

(65) That is (the Paradise) whereof Allah gives glad tidings to His slaves who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds. Say (O Muhammad صلى الله عليه و سلم): "No reward do I ask of you for this except to be kind to me for my kinship with you." And whoever earns a good righteous deed, We shall give him an increase of good in respect thereof. Verily, Allah is Oft-Forgiving, Most Ready to appreciate (the deeds of those who are obedient to Him).

(66) And whatever of misfortune befalls you, it is because of what your hands have earned. And He pardons much. (See the Qur'an Verse 35:45).

(67) Or He may destroy them (by shipwreck) because of that which their (people) have earned. And He pardons much.

(68) And when he learns something of Our Verses (this Qur'an), he makes them a jest. For such there will be a humiliating torment.

(69) In front of them there is Hell. And that which they have earned will be of no profit to them, nor (will be of any profit to them) those whom they have taken as Auliya' (protectors, helpers) besides Allah. And theirs will be a great torment.

(70) Say (O Muhammad صلى الله عليه و سلم) to the believers to forgive those who (harm them and) hope not for the Days of Allah (i.e. His Recompense), that He may recompense people, according to what they have earned (i.e. to punish these disbelievers who harm the believers).
