We will relate to thee their tidings truly. They were youths who believed in their Lord, and We increased them in guidance. 13 And We made firm their hearts when they stood forth and said: Our Lord is the Lord of the heavens and the earth. We cry unto no Allah beside Him, for then should we utter an enormity. 14 These people of ours have taken deities other than Him. Why do they not produce clear evidence about them? Who is more wicked than the man who invents a falsehood against God? 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 [for many a year] thou might have seen the sun, on its rising, incline away from their cave on the right, and on its setting, turn aside from them on the left, while they lived on in that spacious chamber, [bearing witness to] this of God's messages: He whom God guides, he alone has found the right way; whereas for him whom He lets go astray thou canst never find any protector who would point out the right way. 17
