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

(1) 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!"

(2) And the Unbelievers will say: "Our Lord! Show us those, among Jinns and men, who misled us: We shall crush them beneath our feet, so that they become the vilest (before all)."
