We relate to you their story with the truth; surely 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 for themselves gods beside Him - wherefore bring they not for them an authority manifest? and who doth greater wrong than he who fabricateth against God a lie? 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
