It is We who relate to you, [O Muhammad], their story in truth. Indeed, they were youths who believed in their Lord, and We increased 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 nation have taken to themselves gods, other than Allah. Why do they not bring some clear authority regarding them! Who does greater evil than he who forges a lie against Allah' 15 (They were told), "Now that you have abandoned them and what they worship instead of God, seek refuge in the cave. God will, certainly, grant you mercy and provide you with help to safely get out of this trouble." 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
