The word(s) "sins" appears 134 time(s) in 127 verse(s) in Quran in Mohsin Khan translation.

(121) And they will not receive admonition unless Allah wills; He (Allah) is the One, deserving that mankind should be afraid of, and should be dutiful to Him, and should not take any Ilah (god) along with Him, and He is the One Who forgives (sins).

(122) Nay! Man (denies Resurrection and Reckoning. So he) desires to continue committing sins.

(123) Go to Fir'aun (Pharaoh); verily he has transgressed all bounds (in crimes, sins, polytheism, disbelief).

(124) And how can you know that he might become pure (from sins)?

(125) Nay! But on their hearts is the Ran (covering of sins and evil deeds) which they used to earn.

(126) There is indeed in them (the above oaths) sufficient proofs for men of understanding (and that, they should avoid all kinds of sins and disbeliefs)!

(127) Except those who believe (in Islamic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (Al-Ma'ruf) which Allah has ordained, and abstain from all kinds of sins and evil deeds (Al-Munkar which Allah has forbidden], and recommend one another to patience (for the sufferings, harms, and injuries which one may encounter in Allah's Cause during preaching His religion of Islamic Monotheism or Jihad).
