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 And We made firm their hearts when they stood up and said, "Our Lord is the Lord of the heavens and the earth. Never will we invoke besides Him any deity. We would have certainly spoken, then, an excessive transgression. 14 These our people have taken to them other gods, apart from Him. Ah, if only they would bring some clear authority regarding them! But who does greater evil than he who forges against God 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 ۞ 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
