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 (Then they conferred among themselves and said): "These men, our own people, have taken others as gods beside Him: why do they not bring any clear evidence that they indeed are gods? Who can be more unjust than he who foists a lie on 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 ۞ 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
