The word(s) "sin" appears 346 time(s) in 329 verse(s) in Quran in Abdullah Yusuf Ali translation.

(191) He said: "This has been given to me because of a certain knowledge which I have." Did he not know that Allah had destroyed, before him, (whole) generations,- which were superior to him in strength and greater in the amount (of riches) they had collected? but the wicked are not called (immediately) to account for their sins.

(192) We (once) sent Noah to his people, and he tarried among them a thousand years less fifty: but the Deluge overwhelmed them while they (persisted in) sin.

(193) Now, if they embark on a boat, they call on Allah, making their devotion sincerely (and exclusively) to Him; but when He has delivered them safely to (dry) land, behold, they give a share (of their worship to others)!-

(194) And among His Signs is this, that heaven and earth stand by His Command: then when He calls you, by a single call, from the earth, behold, ye (straightway) come forth.

(195) It is Allah Who has created you: further, He has provided for your sustenance; then He will cause you to die; and again He will give you life. Are there any of your (false) "Partners" who can do any single one of these things? Glory to Him! and high is He above the partners they attribute (to him)!

(196) When a wave covers them like the canopy (of clouds), they call to Allah, offering Him sincere devotion. But when He has delivered them safely to land, there are among them those that halt between (right and wrong). But none reject Our Signs except only a perfidious ungrateful (wretch)!

(197) He it is Who sends blessings on you, as do His angels, that He may bring you out from the depths of Darkness into Light: and He is Full of Mercy to the Believers.

(198) Allah and His angels send blessings on the Prophet: O ye that believe! Send ye blessings on him, and salute him with all respect.

(199) And those who annoy believing men and women undeservedly, bear (on themselves) a calumny and a glaring sin.

(200) That He may make your conduct whole and sound and forgive you your sins: He that obeys Allah and His Messenger, has already attained the highest achievement.
