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

(41) And all married women (are forbidden unto you) save those (captives) whom your right hands possess. It is a decree of Allah for you. Lawful unto you are all beyond those mentioned, so that ye seek them with your wealth in honest wedlock, not debauchery. And those of whom ye seek content (by marrying them), give unto them their portions as a duty. And there is no sin for you in what ye do by mutual agreement after the duty (hath been done). Lo! Allah is ever Knower, Wise.

(42) And whoso is not able to afford to marry free, believing women, let them marry from the believing maids whom your right hands possess. Allah knoweth best (concerning) your faith. Ye (proceed) one from another; so wed them by permission of their folk, and give unto them their portions in kindness, they being honest, not debauched nor of loose conduct. And if when they are honourably married they commit lewdness they shall incur the half of the punishment (prescribed) for free women (in that case). This is for him among you who feareth to commit sin. But to have patience would be better for you. Allah is Forgiving, Merciful.

(43) Lo! Allah forgiveth not that a partner should be ascribed unto Him. He forgiveth (all) save that to whom He will. Whoso ascribeth partners to Allah, he hath indeed invented a tremendous sin.

(44) See, how they invent lies about Allah! That of itself is flagrant sin.

(45) Lo! among you there is he who loitereth; and if disaster overtook you, he would say: Allah hath been gracious unto me since I was not present with them.

(46) O ye who believe! When ye go forth (to fight) in the way of Allah, be careful to discriminate, and say not unto one who offereth you peace: "Thou art not a believer," seeking the chance profits of this life (so that ye may despoil him). With Allah are plenteous spoils. Even thus (as he now is) were ye before; but Allah hath since then been gracious unto you. Therefore take care to discriminate. Allah is ever Informed of what ye do.

(47) And when ye go forth in the land, it is no sin for you to curtail (your) worship if ye fear that those who disbelieve may attack you. In truth the disbelievers are an open enemy to you.

(48) And when thou (O Muhammad) art among them and arrangest (their) worship for them, let only a party of them stand with thee (to worship) and let them take their arms. Then when they have performed their prostrations let them fall to the rear and let another party come that hath not worshipped and let them worship with thee, and let them take their precaution and their arms. Those who disbelieve long for you to neglect your arms and your baggage that they may attack you once for all. It is no sin for you to lay aside your arms, if rain impedeth you or ye are sick. But take your precaution. Lo! Allah prepareth for the disbelievers shameful punishment.

(49) And plead not on behalf of (people) who deceive themselves. Lo! Allah loveth not one who is treacherous and sinful.

(50) They seek to hide from men and seek not to hide from Allah. He is with them when by night they hold discourse displeasing unto Him. Allah ever surroundeth what they do.
