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

(111) Say (O Muhammad صلى الله عليه وسلم): "I find not in that which has been revealed to me anything forbidden to be eaten by one who wishes to eat it, unless it be Maitah (a dead animal) or blood poured forth (by slaughtering or the like), or the flesh of swine (pork); for that surely is impure or impious (unlawful) meat (of an animal) which is slaughtered as a sacrifice for others than Allah (or has been slaughtered for idols, or on which Allah's Name has not been mentioned while slaughtering). But whosoever is forced by necessity without wilful disobedience, nor transgressing due limits; (for him) certainly, your Lord is Oft-Forgiving, Most Merciful."

(112) If they (Jews) belie you (Muhammad صلى الله عليه وسلم) say: "Your Lord is the Owner of Vast Mercy, and never will His Wrath be turned back from the people who are Mujrimun (criminals, polytheists or sinners)."

(113) Say (O Muhammad صلى الله عليه وسلم): "Come, I will recite what your Lord has prohibited you from: Join not anything in worship with Him; be good and dutiful to your parents; kill not your children because of poverty - We provide sustenance for you and for them; come not near to Al-Fawahish (shameful sins, illegal sexual intercourse) whether committed openly or secretly; and kill not anyone whom Allah has forbidden, except for a just cause (according to Islamic law). This He has commanded you that you may understand.

(114) 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."

(115) 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."

(116) And he [Shaitan (Satan)] swore by Allah to them both (saying): "Verily, I am one of the sincere well-wishers for you both."

(117) Say (O Muhammad صلى الله عليه وسلم): My Lord has commanded justice and (said) that you should face Him only (i.e. worship none but Allah and face the Qiblah, i.e. the Ka'bah at Makkah during prayers) in every place of worship, in prayers (and not to face other false deities and idols), and invoke Him only making your religion sincere to Him (by not joining in worship any partner with Him and with the intention that you are doing your deeds for Allah's sake only). As He brought you (into being) in the beginning, so shall you be brought into being [on the Day of Resurrection in two groups, one as a blessed one (believers), and the other as a wretched one (disbelievers)].

(118) Say (O Muhammad صلى الله عليه وسلم): "(But) the things that my Lord has indeed forbidden are Al-Fawahish (great evil sins and every kind of unlawful sexual intercourse) whether committed openly or secretly, sins (of all kinds), unrighteous oppression, joining partners (in worship) with Allah for which He has given no authority, and saying things about Allah of which you have no knowledge."

(119) Verily, those who belie Our Ayat (proofs, evidence, verses, lessons, signs, revelations) and treat them with arrogance, for them the gates of heaven will not be opened, and they will not enter Paradise until the camel goes through the eye of the needle (which is impossible). Thus do We recompense the Mujrimun (criminals, polytheists and sinners).

(120) "I convey unto you the Messages of my Lord and give sincere advice to you. And I know from Allah what you know not.
