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 and said: 'Our Lord is the Lord of the heavens and the earth. We will call on no other god except Him; (for if we did), we would have spoken outrageously (in disbelief), 14 These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah 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 ۞ 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
