The word(s) "guilty" appears 16 time(s) in 15 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) On the Day that the Hour will be established, the guilty will be struck dumb with despair.

(12) If only thou couldst see when the guilty ones will bend low their heads before their Lord, (saying:) "Our Lord! We have seen and we have heard: Now then send us back (to the world): we will work righteousness: for we do indeed (now) believe."

(13) O Consorts of the Prophet! If any of you were guilty of evident unseemly conduct, the Punishment would be doubled to her, and that is easy for Allah.

(14) What! Are they better than the people of Tubba and those who were before them? We destroyed them because they were guilty of sin.

(15) O Prophet! When ye do divorce women, divorce them at their prescribed periods, and count (accurately), their prescribed periods: And fear Allah your Lord: and turn them not out of their houses, nor shall they (themselves) leave, except in case they are guilty of some open lewdness, those are limits set by Allah: and any who transgresses the limits of Allah, does verily wrong his (own) soul: thou knowest not if perchance Allah will bring about thereafter some new situation.
