We narrate unto thee their story with truth. Lo! they were young men who believed in their Lord, and We increased them in guidance. 13 and strengthened their hearts when they stood up and proclaimed: "Our Lord is the Lord of the heavens and the earth. We shall call upon no other god beside Him; (for if we did so), we shall be uttering a blasphemy." 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support of their beliefs; and who could be more wicked than he who invents a lie about God? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your [outward] condition - with all that your souls may need! 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
