We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced them in guidance: 13 We gave strength to their hearts: Behold, they stood up and said: "Our Lord is the Lord of the heavens and of the earth: never shall we call upon any god other than Him: if we did, we should indeed have uttered an enormity! 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 And who doth greater wrong than he who inventeth a lie concerning Allah? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your [outward] condition - with all that your souls may need! 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
