The word(s) "sin" appears 521 time(s) in 480 verse(s) in Quran in Mohsin Khan translation.

(11) Similarly (to complete My Blessings on you), We have sent among you a Messenger (Muhammad صلى الله عليه وسلم) of your own, reciting to you Our Verses (the Qur'an) and purifying you, and teaching you the Book (the Qur'an) and the Hikmah (i.e. Sunnah, Islamic laws and Fiqh - jurisprudence), and teaching you that which you used not to know.

(12) Verily! As-Safa and Al-Marwah (two mountains in Makkah) are of the Symbols of Allah. So it is not a sin on him who performs Hajj or 'Umrah (pilgrimage) of the House (the Ka'bah at Makkah) to perform the going (Tawaf) between them (As-Safa and Al-Marwah). And whoever does good voluntarily, then verily, Allah is All-Recogniser, All-Knower.

(13) He [Shaitan (Satan)] commands you only what is evil and Fahsha (sinful), and that you should say against Allah what you know not.

(14) He has forbidden you only the Maitah (dead animals), and blood, and the flesh of swine, and that which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols, on which Allah's Name has not been mentioned while slaughtering). But if one is forced by necessity without wilful disobedience nor transgressing due limits, then there is no sin on him. Truly, Allah is Oft-Forgiving, Most Merciful.

(15) Then whoever changes the bequest after hearing it, the sin shall be on those who make the change. Truly, Allah is All-Hearer, All-Knower.

(16) But he who fears from a testator some unjust act or wrong-doing, and thereupon he makes peace between the parties concerned, there shall be no sin on him. Certainly, Allah is Oft-Forgiving, Most Merciful.

(17) And eat up not one another's property unjustly (in any illegal way e.g. stealing, robbing, deceiving, etc.), nor give bribery to the rulers (judges before presenting your cases) that you may knowingly eat up a part of the property of others sinfully.

(18) And spend in the Cause of Allah (i.e. Jihad of all kinds) and do not throw yourselves into destruction (by not spending your wealth in the Cause of Allah), and do good. Truly, Allah loves Al-Muhsinun (the good-doers).

(19) The Hajj (pilgrimage) is (in) the well-known (lunar year) months (i.e. the 10th month, the 11th month and the first ten days of the 12th month of the Islamic calendar, i.e. two months and ten days). So whosoever intends to perform Hajj therein (by assuming Ihram), then he should not have sexual relations (with his wife), nor commit sin, nor dispute unjustly during the Hajj. And whatever good you do, (be sure) Allah knows it. And take a provision (with you) for the journey, but the best provision is At-Taqwa (piety, righteousness). So fear Me, O men of understanding!

(20) There is no sin on you if you seek the Bounty of your Lord (during pilgrimage by trading). Then when you leave 'Arafat , remember Allah (by glorifying His Praises, i.e. prayers and invocations) at the Mash'ar-il-Haram . And remember Him (by invoking Allah for all good.) as He has guided you, and verily, you were, before, of those who were astray.
