We tell you this story for a genuine purpose. They were young people who believed in their Lord and We gave them further guidance. 13 And We strengthened their hearts, when they stood up and said, 'Our Lord is the Lord of the heavens and earth; we will not call upon any god, apart from Him, or then we had spoken outrage. 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 So, when you have gone apart from them and that they serve, excepting God, take refuge in the Cave, and your Lord will unfold to you of His mercy, and will furnish -- you with a gentle issue of your affair.' 16 ۞ You may well have seen when the sun came up it moved away to the right of the cave, and when it went down it turned away to the left, and they stayed in its open space. This was among the signs of God. Whoever is guided by God follows the right path; and whosoever goes astray will not find a guide to show him the way. 17
