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 strengthened their hearts when they stood up and said: "Our Lord is the Lord of the heavens and the earth. We shall invoke no god beside Him, for we shall have uttered a blasphemy then. 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 ۞ And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend. 17
