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

(61) And how many generations have We destroyed after Nuh (Noah)! And Sufficient is your Lord as an All-Knower and All-Beholder of the sins of His slaves.

(62) 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,

(63) 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).

(64) '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).

(65) 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,

(66) And thus do We requite him who transgresses beyond bounds [i.e. commits the great sins and disobeys his Lord (Allah) and believes not in His Messengers, and His revealed Books, like this Qur'an], and believes not in the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of his Lord; and the torment of the Hereafter is far more severe and more lasting.

(67) Then We fulfilled to them the promise. So We saved them and those whom We willed, but We destroyed Al-Musrifun (i.e. disbelievers in Allah, in His Messengers, extravagants, transgressors of Allah's limits by committing crimes, oppressions, polytheism and sins).

(68) O you who believe! Follow not the footsteps of Shaitan (Satan). And whosoever follows the footsteps of Shaitan (Satan), then, verily he commands Al-Fahsha' [i.e. to commit indecency (illegal sexual intercourse)], and Al-Munkar [disbelief and polytheism (i.e. to do evil and wicked deeds; and to speak or to do what is forbidden in Islam)]. And had it not been for the Grace of Allah and His Mercy on you, not one of you would ever have been pure from sins. But Allah purifies (guides to Islam) whom He wills, and Allah is All-Hearer, All-Knower.

(69) And put your trust (O Muhammad صلى الله عليه وسلم) in the Ever Living One Who dies not, and glorify His Praises, and Sufficient is He as the All-Knower of the sins of His slaves,

(70) Except those who repent and believe (in Islamic Monotheism), and do righteous deeds; for those, Allah will change their sins into good deeds, and Allah is Oft-Forgiving, Most Merciful.
