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

(1) But any that gains a hearing by stealth, is pursued by a flaming fire, bright (to see).

(2) Except such as snatch away something by stealth, and they are pursued by a flaming fire, of piercing brightness.

(3) And thou wilt see them brought forward to the (Penalty), in a humble frame of mind because of (their) disgrace, (and) looking with a stealthy glance. And the Believers will say: "Those are indeed in loss, who have given to perdition their own selves and those belonging to them on the Day of Judgment. Behold! Truly the Wrong-doers are in a lasting Penalty!"
