It is We who relate to you, [O Muhammad], their story in truth. Indeed, they were youths who believed in their Lord, and We increased them in guidance. 13 We strengthened their hearts, when they rose up and declared, "Our Lord is the Lord of the heavens and the earth. Never shall we call upon any deity other than Him: for that would be an outrageous thing to do. 14 These, our people, have taken for themselves gods beside Him - wherefore bring they not for them an authority manifest? and who doth greater wrong than he who fabricateth against God a lie? 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave.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 ۞ Had you seen them in the Cave it would have appeared to you that when the sun rose, it moved away from their Cave to the right; and when it set, it turned away from them to the left, while they remained in a spacious hollow in the Cave. This is one of the Signs of Allah. Whomsoever Allah guides, he alone is led aright; and whomsoever Allah lets go astray, you will find for him no guardian to direct him. 17
