We recount unto thee their tidings with truth. Verily they were certain youths who believed in their Lord, and We increased them in guidance. 13 And We braced their hearts when they stood forth and said: our Lord is the Lord of the heavens and the earth; never we shall call upon a god beside him; for then we shall be saying an abomination. 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 So, when you have gone apart from them and that they serve, excepting God, take refuge in the Cave, and your Lord will unfold to you of His mercy, and will furnish -- you with a gentle issue of your affair.' 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
