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

(161) If only there had been among the generations before you persons having wisdom, prohibiting (others) from Al-Fasad (disbelief, polytheism, and all kinds of crimes and sins) in the earth, (but there were none) - except a few of those whom We saved from among them! Those who did wrong pursued the enjoyment of good things of (this worldly) life, and were Mujrimun (criminals, disbelievers in Allah, polytheists, sinners).

(162) Alif-Lam-Ra. [These letters are one of the miracles of the Qur'an, and none but Allah (Alone) knows their meanings]. These are the Verses of the Clear Book (the Qur'an that makes clear the legal and illegal things, laws, a guidance and a blessing).

(163) "Kill Yusuf (Joseph) or cast him out to some (other) land, so that the favour of your father may be given to you alone, and after that you will be righteous folk (by intending repentance before committing the sin)."

(164) And when he [Yusuf (Joseph)] attained his full manhood, We gave him wisdom and knowledge (the Prophethood); thus We reward the Muhsinun (doers of good - see the footnote of V.9:120).

(165) "O Yusuf (Joseph)! Turn away from this! (O woman!) Ask forgiveness for your sin. Verily, you were of the sinful."

(166) He said: "O my Lord! Prison is dearer to me than that to which they invite me. Unless You turn away their plot from me, I will feel inclined towards them and be one (of those who commit sin and deserve blame or those who do deeds) of the ignorant."

(167) And there entered with him two young men in the prison. One of them said: "Verily, I saw myself (in a dream) pressing wine." The other said: "Verily, I saw myself (in a dream) carrying bread on my head and birds were eating thereof." (They said): "Inform us of the interpretation of this. Verily, we think you are one of the Muhsinun (doers of good)."

(168) Thus did We give full authority to Yusuf (Joseph) in the land, to take possession therein, when or where he likes. We bestow of Our Mercy on whom We will, and We make not to be lost the reward of Al-Muhsinun (the good doers - See V.2:112).

(169) And verily, the reward of the Hereafter is better for those who believe and used to fear Allah and keep their duty to Him (by abstaining from all kinds of sins and evil deeds and by performing all kinds of righteous good deeds).

(170) They said: "O ruler of the land! Verily, he has an old father (who will grieve for him); so take one of us in his place. Indeed we think that you are one of the Muhsinun (good-doers - see the footnote of V.9:120)."
