And you might think them awake while they were asleep and We turned them about to the right and to the left, while their dog (lay) outstretching its paws at the entrance; if you looked at them you would certainly turn back from them in flight, and you would certainly be filled with awe because of them. 18 And thus did We rouse them that they might question each other.
