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 made their hearts steadfast when they stood up and said, “Our Lord is the Lord of the heavens and the earth – we shall not worship any other deity except Him – if it were, we have then said something excessive.” 14 These, our people, have chosen (other) gods beside Him though they bring no clear warrant (vouchsafed) to them. And who doth greater wrong than he who inventeth a lie concerning Allah? 15 (The young men said to one another): "And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the Cave, your Lord will open a way for you from His Mercy and will make easy for you your affair (i.e. will give you what you will need of provision, dwelling, etc.)." 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
