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

(31) "Verily, you practise your lusts on men instead of women. Nay, but you are a people transgressing beyond bounds (by committing great sins)."

(32) And the answer of his people was only that they said: "Drive them out of your town, these are indeed men who want to be pure (from sins)!"

(33) Is it not clear to those who inherit the earth in succession from its (previous) possessors, that had We willed, We would have punished them for their sins. And We seal up their hearts so that they hear not?

(34) And (remember) when it was said to them: "Dwell in this town (Jerusalem) and eat therefrom wherever you wish, and say, '(O Allah) forgive our sins'; and enter the gate prostrate (bowing with humility). We shall forgive you your wrong-doings. We shall increase (the reward) for the good-doers."

(35) Then after them succeeded an (evil) generation, which inherited the Book, but they chose (for themselves) the goods of this low life (evil pleasures of this world) saying (as an excuse): "(Everything) will be forgiven to us." And if (again) the offer of the like (evil pleasures of this world) came their way, they would (again) seize them (would commit those sins). Was not the covenant of the Book taken from them that they would not say about Allah anything but the truth? And they have studied what is in it (the Book). And the home of the Hereafter is better for those who are Al-Muttaqun (the pious - See V.2:2). Do not you then understand?

(36) Or lest you should say: "It was only our fathers afortime who took others as partners in worship along with Allah, and we were (merely their) descendants after them; will You then destroy us because of the deeds of men who practised Al-Batil (i.e. polytheism and committing crimes and sins, invoking and worshipping others besides Allah)?" (Tafsir At-Tabari).

(37) O you who believe! If you obey and fear Allah, He will grant you Furqan [(a criterion to judge between right and wrong), or (Makhraj, i.e. a way for you to get out from every difficulty)], and will expiate for you your sins, and forgive you; and Allah is the Owner of the Great Bounty.

(38) Similar to the behaviour of the people of Fir'aun (Pharaoh), and of those before them - they rejected the Ayat (proofs, verses, etc.) of Allah, so Allah punished them for their sins. Verily, Allah is All-Strong, Severe in punishment.

(39) Similar to the behaviour of the people of Fir'aun (Pharaoh), and those before them. They belied the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of their Lord, so We destroyed them for their sins, and We drowned the people of Fir'aun (Pharaoh) for they were all Zalimun (polytheists and wrong-doers).

(40) So let them laugh a little and (they will) cry much as a recompense of what they used to earn (by committing sins).
