We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced 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 – the people of ours – have set up Gods besides Allah; why do they not bring a clear proof regarding them? And who is more unjust than one who fabricates a lie against Allah?” 15 When you depart from them and from what they worship, other than Allah, seek refuge in the Cave. Allah will extend His Mercy to you and will furnish you with a gentle issue of 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
