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

(31) So if you gain the mastery over them in war, punish them severely in order to disperse those who are behind them, so that they may learn a lesson.

(32) So let them laugh a little and (they will) cry much as a recompense of what they used to earn (by committing sins).

(33) They will swear by Allah to you (Muslims) when you return to them, that you may turn away from them. So turn away from them. Surely, they are Rijs [i.e. Najas (impure) because of their evil deeds], and Hell is their dwelling place - a recompense for that which they used to earn.

(34) And of the bedouins there are some who believe in Allah and the Last Day, and look upon what they spend in Allah's Cause as means of nearness to Allah, and a cause of receiving the Messenger's invocations. Indeed these (spendings in Allah's Cause) are a means of nearness for them. Allah will admit them to His Mercy. Certainly Allah is Oft-Forgiving, Most Merciful.

(35) See they not that they are put in trial once or twice every year (with different kinds of calamities, disease, famine)? Yet, they turn not in repentance, nor do they learn a lesson (from it).

(36) Those, their abode will be the Fire, because of what they used to earn.

(37) And those who have earned evil deeds, the recompense of an evil deed is the like thereof, and humiliating disgrace will cover them (their faces). No defender will they have from Allah. Their faces will be covered as it were with pieces from the darkness of night. They are the dwellers of the Fire, they will abide therein forever.

(38) There! Every person will know (exactly) what he had earned before and they will be brought back to Allah, their rightful Maula (Lord), and their invented false deities will vanish from them.

(39) Then it will be said to them who wronged themselves: "Taste you the everlasting torment! Are you recompensed (aught) save what you used to earn?"

(40) He said: "O my people! Tell me if I have a clear evidence from my Lord and He has given me a good sustenance from Himself (shall I corrupt it by mixing it with the unlawfully earned money). I wish not, in contradiction to you, to do that which I forbid you. I only desire reform to the best of my power. And my guidance cannot come except from Allah, in Him I trust and unto Him I repent.
