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 We made firm their hearts when they stood forth and said: Our Lord is the Lord of the heavens and the earth. We cry unto no Allah beside Him, for then should we utter an enormity. 14 As for these our people here, they have taken to other gods apart from Him. Then why do they not bring a clear authority for them? Who is more wicked than he who fabricates a lie against God?" 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave. Your Lord will spread out for you of His mercy and will prepare for you from your affair facility." 16 ۞ The sun could be observed to incline away from their cave on the right, as it rose, and to turn away from them on the left, when it set, while they lay in the wide space inside the cave. This is one of the signs of God. He whom God guides is rightly guided; but for him whom He lets go astray, you will find no helper or guide. 17
