The word(s) "sin" appears 227 time(s) in 208 verse(s) in Quran in Muhammad Pickthal translation.

(191) O ye who believe! When believing women come unto you as fugitives, examine them. Allah is Best Aware of their faith. Then, if ye know them for true believers, send them not back unto the disbelievers. They are not lawful for them (the disbelievers), nor are they (the disbelievers) lawful for them. And give them (the disbelievers) that which they have spent (upon them). And it is no sin for you to marry such women when ye have given them their dues. And hold not to the ties of disbelieving women; and ask for (the return of) that which ye have spent; and let them (the disbelievers) ask for that which they have spent. That is the judgment of Allah. He judgeth between you. Allah is Knower, Wise.

(192) He will forgive you your sins and bring you into Gardens underneath which rivers flow, and pleasant dwellings in Gardens of Eden. That is the supreme triumph.

(193) And (He will give you) another (blessing) which ye love: help from Allah and present victory. Give good tidings (O Muhammad) to believers.

(194) O ye who believe! Turn unto Allah in sincere repentance! It may be that your Lord will remit from you your evil deeds and bring you into Gardens underneath which rivers flow, on the day when Allah will not abase the Prophet and those who believe with him. Their light will run before them and on their right hands; they will say: Our Lord! Perfect our light for us, and forgive us! Lo! Thou art Able to do all things.

(195) So they acknowledge their sins; but far removed (from mercy) are the dwellers in the flames.

(196) Have they not seen the birds above them spreading out their wings and closing them? Naught upholdeth them save the Beneficent. Lo! He is Seer of all things.

(197) Which none but sinners eat.

(198) But nay! I swear by the Lord of the rising-places and the setting-places of the planets that We verily are Able

(199) That He may forgive you somewhat of your sins and respite you to an appointed term. Lo! the term of Allah, when it cometh, cannot be delayed, if ye but knew.

(200) Because of their sins they were drowned, then made to enter a Fire. And they found they had no helpers in place of Allah.
