We will relate to thee their tidings truly. 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 (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 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 ۞ And [had you been present], you would see the sun when it rose, inclining away from their cave on the right, and when it set, passing away from them on the left, while they were [laying] within an open space thereof. That was from the signs of Allah. He whom Allah guides is the [rightly] guided, but he whom He leaves astray - never will you find for him a protecting guide. 17
