We relate to thee their story in truth: they were youths who believed in their Lord, and We advanced them in guidance: 13 We strengthened their hearts when they stood up against the idols and said, "Our Lord is the Lord of the heavens and the earth. We shall never worship anyone other than Him lest we commit blasphemy. 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But who does greater evil than he who forges against God a lie? 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave.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 ۞ And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend. 17
