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 We strengthened their hearts when they stood up against the idols and said, "Our Lord is the Lord of the heavens and the earth. We shall never worship anyone other than Him lest we commit blasphemy. 14 These, our people, have taken for themselves gods beside Him - wherefore bring they not for them an authority manifest? and who doth greater wrong than he who fabricateth against God a lie? 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 ۞ 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
