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

(381) Those who avoid great sins (See the Qur'an, Verses: 6:152,153) and Al-Fawahish (illegal sexual intercourse) except the small faults, - verily, your Lord is of Vast Forgiveness. He knows you well when He created you from the earth (Adam), and when you were fetuses in your mothers' wombs. So ascribe not purity to yourselves. He knows best him who fears Allah and keeps his duty to Him [i.e. those who are Al-Muttaqun (the pious. See V.2:2)].

(382) That no burdened person (with sins) shall bear the burden (sins) of another.

(383) And the people of Nuh (Noah) aforetime. Verily, they were more unjust and more rebellious and transgressing [in disobeying Allah and His Messenger Nuh (Noah) عليه السلام].

(384) Wasting your (precious) lifetime in pastime and amusements (singing, etc.).

(385) Verily, We sent against them a single Saihah (torment - awful cry), and they became like the stubble of a fold-builder.

(386) Verily the Mujrimun (polytheists, disbelievers, sinners, criminals) are in error (in this world) and will burn (in the Hell-fire in the Hereafter).

(387) Therein are fruits and date-palms producing sheathed fruit-stalks (enclosing dates).

(388) Then which of the Blessings of your Lord will you both (jinn and men) deny?

(389) Then which of the Blessings of your Lord will you both (jinn and men) deny?

(390) Then which of the Blessings of your Lord will you both (jinn and men) deny?
