Sura 18, Al-Kahf (The Cave)
18:18
And you (would) think them
awake
while they
(were) asleep.
And We turned them
to
the right
and to
the left,
while their dog
stretched
his two forelegs
at the entrance.
If
you had looked
at them,
you (would) have surely turned back
from them
(in) flight
and surely you would have been filled
by them
(with) terror.
