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

(41) Is then He (Allah) Who takes charge (guards, maintains, provides) of every person and knows all that he has earned (like any other deities who know nothing)? Yet, they ascribe partners to Allah. Say: "Name them! Is it that you will inform Him of something He knows not in the earth or is it (just) a show of false words." Nay! To those who disbelieved, their plotting is made fairseeming, and they have been hindered from the Right Path; and whom Allah sends astray, for him there is no guide.

(42) And verily, those before them did devise plots, but all planning is Allah's. He knows what every person earns, and the disbelievers will know who gets the good end (final destination).

(43) The parable of those who disbelieved in their Lord is that their works are as ashes, on which the wind blows furiously on a stormy day; they shall not be able to get aught of what they have earned. That is the straying, far away (from the Right Path).

(44) That Allah may requite each person according to what he has earned. Truly, Allah is Swift at reckoning.

(45) Surely! In this are signs for those who see (or understand or learn the lessons from the Signs of Allah).

(46) And all that they used to earn availed them not.

(47) And We sent not (as Our Messengers) before you (O Muhammad صلى الله عليه و سلم) any but men, whom We sent revelation, (to preach and invite mankind to believe in the Oneness of Allah). So ask (you, O pagans of Makkah) of those who know the Scripture [learned men of the Taurat (Torah) and the Injeel (Gospel)], if you know not.

(48) "And befool them gradually those whom you can among them with your voice (i.e. songs, music, and any other call for Allah's disobedience), make assaults on them with your cavalry and your infantry, share with them wealth and children (by tempting them to earn money by illegal ways - usury, or by committing illegal sexual intercourse), and make promises to them." But Satan promises them nothing but deceit.

(49) And your Lord is Most Forgiving, Owner of Mercy. Were He to call them to account for what they have earned, then surely, He would have hastened their punishment. But they have their appointed time, beyond which they will find no escape.

(50) Then We sent Our Messengers in succession. Every time there came to a nation their Messenger, they denied him; so We made them follow one another (to destruction), and We made them as Ahadith (the true stories for mankind to learn a lesson from them). So away with a people who believe not!
