18:18You would think them awake, although they were asleep. And We turned them over to the right, and to the left, with their dog stretching its paws across the threshold. Had you looked at them, you would have turned away from them in flight, and been filled with fear of them.

18:49And the book will be placed, and you will see the sinners fearful of its contents. And they will say, “Woe to us! What is with this book that leaves nothing, small or big, but it has enumerated it?” They will find everything they had done present. Your Lord does not wrong anyone.

18:80As for the boy, his parents were believers, and we feared he would overwhelm them with oppression and disbelief.
