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 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 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 when you forsake them and what they worship save Allah, betake yourselves for refuge to the cave; your Lord will extend to you largely of His mercy and provide for you a profitable course in your affair. 16 ۞ You may well have seen when the sun came up it moved away to the right of the cave, and when it went down it turned away to the left, and they stayed in its open space. This was among the signs of God. Whoever is guided by God follows the right path; and whosoever goes astray will not find a guide to show him the way. 17
