The word(s) "innocent" appears 3 time(s) in 3 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) But if any one earns a fault or a sin and throws it on to one that is innocent, He carries (on himself) (Both) a falsehood and a flagrant sin.

(2) Say: "What thing is most weighty in evidence?" Say: "Allah is witness between me and you; This Qur'an hath been revealed to me by inspiration, that I may warn you and all whom it reaches. Can ye possibly bear witness that besides Allah there is another Allah?" Say: "Nay! I cannot bear witness!" Say: "But in truth He is the one Allah, and I truly am innocent of (your blasphemy of) joining others with Him."

(3) Then they proceeded: until, when they met a young man, he slew him. Moses said: "Hast thou slain an innocent person who had slain none? Truly a foul (unheard of) thing hast thou done!"
