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

(101) And thus do We explain the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail, that the way of the Mujrimun (criminals, polytheists, sinners) may become manifest.

(102) When he saw the moon rising up, he said: "This is my lord." But when it set, he said: "Unless my Lord guides me, I shall surely be among the people who went astray."

(103) When he saw the sun rising up, he said: "This is my lord. This is greater." But when it set, he said: "O my people! I am indeed free from all that you join as partners (in worship with Allah).

(104) And We bestowed upon him Ishaq (Isaac) and Ya'qub (Jacob), each of them We guided, and before him, We guided Nuh (Noah), and among his progeny Dawud (David), Sulaiman (Solomon), Ayyub (Job), Yusuf (Joseph), Musa (Moses), and Harun (Aaron). Thus do We reward Al-Muhsinun (the good-doers - see the footnote of V.9: 120).

(105) They (the Jews, Quraish pagans, idolaters) did not estimate Allah with an estimation due to Him when they said: "Nothing did Allah send down to any human being (by revelation)." Say (O Muhammad صلى الله عليه وسلم): "Who then sent down the Book which Musa (Moses) brought, a light and a guidance to mankind which you (the Jews) have made into (separate) papersheets, disclosing (some of it) and concealing much. And you (believers in Allah and His Messenger Muhammad صلى الله عليه وسلم) were taught (through the Qur'an) that which neither you nor your fathers knew." Say: "Allah (sent it down)." Then leave them to play in their vain discussions. (Tafsir Al-Qurtubi).

(106) It is He Who has created you from a single person (Adam), and has given you a place of residing (on the earth or in your mother's wombs) and a place of storage [in the earth (in your graves) or in your father's loins]. Indeed, We have explained in detail Our revelations (this Qur'an) for people who understand.

(107) (And this is in order) that the hearts of those who disbelieve in the Hereafter may incline to such (deceit), and that they may remain pleased with it, and that they may commit what they are committing (all kinds of sins and evil deeds).

(108) Leave (O mankind, all kinds of) sin, open and secret. Verily, those who commit sin will get due recompense for that which they used to commit.

(109) Eat not (O believers) of that (meat) on which Allah's Name has not been pronounced (at the time of the slaughtering of the animal), for sure it is Fisq (a sin and disobedience of Allah). And certainly, the Shayatin (devils) do inspire their friends (from mankind) to dispute with you, and if you obey them [by making Al-Maitah (a dead animal) legal by eating it], then you would indeed be Mushrikun (polytheists); [because they (devils and their friends) made lawful to you to eat that which Allah has made unlawful to eat and you obeyed them by considering it lawful to eat, and by doing so you worshipped them; and to worship others besides Allah is polytheism].

(110) And when there comes to them a sign (from Allah) they say: "We shall not believe until we receive the like of that which the Messengers of Allah had received." Allah knows best with whom to place His Message. Humiliation and disgrace from Allah and a severe torment will overtake the criminals (polytheists, sinners) for that which they used to plot.
