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 We strengthened their hearts when they stood up and said: 'Our Lord is the Lord of the heavens and the earth. We will call on no other god except Him; (for if we did), we would have spoken outrageously (in disbelief), 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greater wrong than he who inventeth a lie concerning Allah? 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave.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 O dear Prophet (Mohammed – peace and blessings be upon him) you will see the sun that when it rises it shifts away to the right of their cave, and when it sets it shifts away to their left, and they are in the open ground of that cave; this is from among the signs of Allah; whomever Allah guides – only he is therefore guided; and whomever He sends astray – you will never find for him a friend who guides. 17
