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

(11) And be afraid of the Day when you shall be brought back to Allah. Then every person shall be paid what he earned, and they shall not be dealt with unjustly.

(12) Allah burdens not a person beyond his scope. He gets reward for that (good) which he has earned, and he is punished for that (evil) which he has earned. "Our Lord! Punish us not if we forget or fall into error, our Lord! Lay not on us a burden like that which You did lay on those before us (Jews and Christians); our Lord! Put not on us a burden greater than we have strength to bear. Pardon us and grant us Forgiveness. Have mercy on us. You are our Maula (Patron, Supporter and Protector, etc.) and give us victory over the disbelieving people. "

(13) How (will it be) when We gather them together on the Day about which there is no doubt (i.e. the Day of Resurrection). And each person will be paid in full what he has earned? And they will not be dealt with unjustly.

(14) It is not (possible) for any human being to whom Allah has given the Book and Al-Hukm (the knowledge and understanding of the laws of religion) and Prophethood to say to the people: "Be my worshippers rather than Allah's." On the contrary (he would say): "Be you Rabbaniyyun (learned men of religion who practise what they know and also preach others), because you are teaching the Book, and you are studying it."

(15) And many a Prophet (i.e. many from amongst the Prophets) fought (in Allah's Cause) and along with him (fought) large bands of religious learned men. But they never lost heart for that which did befall them in Allah's Way, nor did they weaken nor degrade themselves. And Allah loves As-Sabirun (the patient).

(16) Those of you who turned back on the day the two hosts met (i.e. the battle of Uhud), it was Shaitan (Satan) who caused them to backslide (run away from the battlefield) because of some (sins) they had earned. But Allah, indeed, has forgiven them. Surely, Allah is Oft-Forgiving, Most Forbearing.

(17) It is not for any Prophet to take illegally a part of booty (Ghulul ), and whosoever deceives his companions as regards the booty, he shall bring forth on the Day of Resurrection that which he took (illegally). Then every person shall be paid in full what he has earned, and they shall not be dealt with unjustly.

(18) And wish not for the things in which Allah has made some of you to excel others. For men there is reward for what they have earned, (and likewise) for women there is reward for what they have earned, and ask Allah of His Bounty. Surely, Allah is Ever All-Knower of everything.

(19) Then what is the matter with you that you are divided into two parties about the hypocrites? Allah has cast them back (to disbelief) because of what they have earned. Do you want to guide him whom Allah has made to go astray? And he whom Allah has made to go astray, you will never find for him any way (of guidance).

(20) And whoever earns sin, he earns it only against himself. And Allah is Ever All-Knowing, All-Wise.
