The word(s) "guiltless" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) He hath only forbidden you dead meat, and blood, and the flesh of swine, and that on which any other name hath been invoked besides that of Allah. But if one is forced by necessity, without wilful disobedience, nor transgressing due limits,- then is he guiltless. For Allah is Oft-forgiving Most Merciful.

(2) She said: "There before you is the man about whom ye did blame me! I did seek to seduce him from his (true) self but he did firmly save himself guiltless!.... and now, if he doth not my bidding, he shall certainly be cast into prison, and (what is more) be of the company of the vilest!"
