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 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 – the people of ours – have set up Gods besides Allah; why do they not bring a clear proof regarding them? And who is more unjust than one who fabricates a lie against Allah?” 15 "Now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave; your Lord will extend His mercy to you and will make fitting provision for you in your situation." 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
