We narrate unto thee their story with truth. Lo! they were young men 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 people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah 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 ۞ And thou woudst behold the sun when it riseth veering away from their cave on the right, and when it setteth, passing them by on the left, while they were in the spacious part thereof; that is of the signs of Allah. Whomsoever Allah guideth, he indeed is the guided; and whomsoever He sendeth astray, for him thou wilt never find a directing friend. 17
