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 firm their hearts when they stood forth and said: Our Lord is the Lord of the heavens and the earth. We cry unto no Allah beside Him, for then should we utter an enormity. 14 These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah 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 ۞ And thou mightest have seen the sun, when it rose, inclining from their Cave towards the right, and, when it set, passing them by on the left, while they were in a broad fissure of the Cave. That was one of God's signs; whomsoever God guides, he is rightly guided, and whomsoever He leads astray, thou wilt not find for him a protector to direct. 17
