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

(211) And the Mujrimun (criminals, polytheists, sinners) shall see the Fire and apprehend that they have to fall therein. And they will find no way of escape from there.

(212) Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun.

(213) And (made him) sympathetic to men as a mercy (or a grant) from Us, and pure from sins [i.e. Yahya (John)] and he was righteous,

(214) So make no haste against them; We only count out to them a (limited) number (of the days of the life of this world and delay their term so that they may increase in evil and sins).

(215) And We shall drive the Mujrimun (polytheists, sinners, criminals, disbelievers in the Oneness of Allah) to Hell, in a thirsty state (like a thirsty herd driven down to water).

(216) And how many a generation before them have We destroyed! Can you (O Muhammad صلى الله عليه وسلم) find a single one of them or hear even a whisper of them?

(217) Verily whoever comes to his Lord as a Mujrim (criminal, polytheist, sinner, disbeliever in the Oneness of Allah and His Messengers), then surely, for him is Hell, wherein he will neither die nor live.

(218) 'Adn (Eden) Paradise (everlasting Gardens), under which rivers flow, wherein they will abide forever: such is the reward of those who purify themselves (by abstaining from all kinds of sins and evil deeds which Allah has forbidden and by doing all that Allah has ordained).

(219) Whoever turns away from it (this Qur'an - i.e. does not believe in it, nor acts on its orders), verily, they will bear a heavy burden (of sins) on the Day of Resurrection,

(220) The Day when the Trumpet will be blown (the second blowing): that Day, We shall gather the Mujrimun (criminals, polytheists, sinners, disbelievers in the Oneness of Allah) blue or blind-eyed with thirst.
