We tell you this story for a genuine purpose. They were young people who believed in their Lord and We gave them further guidance. 13 And We strengthened their hearts with patience, when they stood up and said: Our Lord is the Lord of the heavens and the earth; we will by no means call upon any god besides Him, for then indeed we should have said an extravagant thing. 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 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 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
