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

(81) Evil (sins and disobedience to Allah) has appeared on land and sea because of what the hands of men have earned (by oppression and evil deeds), that He (Allah) may make them taste a part of that which they have done, in order that they may return (by repenting to Allah, and begging His Pardon).

(82) And indeed We did send Messengers before you (O Muhammad صلى الله عليه وسلم) to their own peoples. They came to them with clear proofs, then, We took vengeance on those who committed crimes (disbelief, setting partners in worship with Allah, sins); and (as for) the believers, it was incumbent upon Us to help (them).

(83) So on that Day no excuse of theirs will avail those who did wrong (by associating partners in worship with Allah, and by denying the Day of Resurrection), nor will they be allowed (then) to return to seek Allah's Pleasure (by having Islamic Faith with righteous deeds and by giving up polytheism, sins and crimes with repentance).

(84) And stay in your houses, and do not display yourselves like that of the times of ignorance, and perform As-Salat (Iqamat-as-Salat), and give Zakat and obey Allah and His Messenger. Allah wishes only to remove Ar-Rijs (evil deeds and sins) from you, O members of the family (of the Prophet صلى الله عليه وسلم), and to purify you with a thorough purification.

(85) He will direct you to do righteous good deeds and will forgive you your sins. And whosoever obeys Allah and His Messenger (صلى الله عليه وسلم), he has indeed achieved a great achievement (i.e. he will be saved from the Hell-fire and will be admitted to Paradise).

(86) They worked for him as he desired, (making) high rooms, images, basins as large as reservoirs, and (cooking) cauldrons fixed (in their places). "Work you, O family of Dawud (David), with thanks!" But few of My slaves are grateful.

(87) Say (O Muhammad صلى الله عليه وسلم to polytheists, pagans) "You will not be asked about our sins, nor shall we be asked of what you do."

(88) And no bearer of burdens shall bear another's burden; and if one heavily laden calls another to (bear) his load, nothing of it will be lifted even though he be near of kin. You (O Muhammad صلى الله عليه وسلم) can warn only those who fear their Lord unseen and perform As-Salat (Iqamat-as-Salat). And he who purifies himself (from all kinds of sins), then he purifies only for the benefit of his ownself. And to Allah is the (final) Return (of all).

(89) They (Messengers) said: "Your evil omens be with you! (Do you call it "evil omen") because you are admonished? Nay, but you are a people Musrifun (transgressing all bounds by committing all kinds of great sins, and by disobeying Allah).

(90) And you will be requited nothing except for what you used to do (evil deeds, sins, and Allah's disobedience which you used to do in this world)
