We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced them in guidance: 13 We gave strength to their hearts: Behold, they stood up and said: "Our Lord is the Lord of the heavens and of the earth: never shall we call upon any god other than Him: if we did, we should indeed have uttered an enormity! 14 These our people have taken to them other gods, apart from Him. Ah, if only they would bring some clear authority regarding them! But who does greater evil than he who forges against God a lie? 15 (And they said to each other:) "Now that you have withdrawn from them and what they worship beside God, it is better to take refuge in the cave. Your Lord may bestow of His mercy on you, and facilitate your affair." 16 ۞ And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidences, signs) of Allah. He whom Allah guides, is rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path). 17
