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

(21) And whoever earns a fault or a sin and then throws it on to someone innocent, he has indeed burdened himself with falsehood and a manifest sin.

(22) Why do not the rabbis and the religious learned men forbid them from uttering sinful words and from eating illegal things. Evil indeed is that which they have been performing.

(23) And He is Allah (to be worshipped Alone) in the heavens and on the earth; He knows what you conceal and what you reveal, and He knows what you earn (good or bad). (See V.43:84)

(24) And leave alone those who take their religion as play and amusement, and whom the life of this world has deceived. But remind (them) with it (the Qur'an) lest a person be given up to destruction for that which he has earned, when he will find for himself no protector or intercessor besides Allah, and even if he offers every ransom, it will not be accepted from him. Such are they who are given up to destruction because of that which they have earned. For them will be a drink of boiling water and a painful torment because they used to disbelieve.

(25) And thus We do make the Zalimun (polytheists and wrong-doers) Auliya' (supporters and helpers) of one another (in committing crimes), because of that which they used to earn.

(26) Do they then wait for anything other than that the angels should come to them, or that your Lord (Allah) should come, or that some of the Signs of your Lord should come (i.e. portents of the Hour e.g., rising of the sun from the west)! The day that some of the Signs of your Lord do come, no good will it do to a person to believe then, if he believed not before, nor earned good (by performing deeds of righteousness) through his Faith. Say: "Wait you! we (too) are waiting."

(27) Say: "Shall I seek a lord other than Allah, while He is the Lord of all things? No person earns any (sin) except against himself (only), and no bearer of burdens shall bear the burden of another. Then unto your Lord is your return, so He will tell you that wherein you have been differing."

(28) The first of them will say to the last of them: "You were not better than us, so taste the torment for what you used to earn."

(29) And if the people of the towns had believed and had the Taqwa (piety), certainly, We should have opened for them blessings from the heaven and the earth, but they belied (the Messengers). So We took them (with punishment) for what they used to earn (polytheism and crimes).

(30) I shall turn away from My Ayat (verses of the Qur'an) those who behave arrogantly on the earth, without a right, and (even) if they see all the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.), they will not believe in them. And if they see the way of righteousness (monotheism, piety, and good deeds), they will not adopt it as the Way, but if they see the way of error (polytheism, crimes and evil deeds), they will adopt that way, that is because they have rejected Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and were heedless (to learn a lesson) from them.
