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 strengthened their hearts, when they stood up and said, 'Our Lord is the Lord of the heavens and earth; we will not call upon any god, apart from Him, or then we had spoken outrage. 14 These people of ours have taken to worshipping [other] deities instead of Him, without being able to adduce any reasonable evidence in support of their beliefs; and who could be more wicked than he who invents a lie about God? 15 "Now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave; your Lord will extend His mercy to you and will make fitting provision for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
