We will relate to thee their tidings truly. They were 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 taken for worship aliha (gods) other than Him (Allah). Why do they not bring for them a clear authority? And who does more wrong than he who invents a lie against 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 ۞ And [had you been present], you would see the sun when it rose, inclining away from their cave on the right, and when it set, passing away from them on the left, while they were [laying] within an open space thereof. That was from the signs of Allah. He whom Allah guides is the [rightly] guided, but he whom He leaves astray - never will you find for him a protecting guide. 17
