We relate to you their story with the truth; surely they were youths who believed in their Lord and We increased them in guidance. 13 And We made firm their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression. 14 These, our people, have chosen (other) gods beside Him though they bring no clear warrant (vouchsafed) to them. And who doth greater wrong than he who inventeth a lie concerning Allah? 15 (And they said to each other:) "Now that you have withdrawn from them and what they worship beside God, it is better to take refuge in the cave. Your Lord may bestow of His mercy on you, and facilitate your affair." 16 ۞ Had you seen them in the Cave it would have appeared to you that when the sun rose, it moved away from their Cave to the right; and when it set, it turned away from them to the left, while they remained in a spacious hollow in the Cave. This is one of the Signs of Allah. Whomsoever Allah guides, he alone is led aright; and whomsoever Allah lets go astray, you will find for him no guardian to direct him. 17
