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 strengthened their hearts when they stood up and said: "Our Lord is the Lord of the heavens and the earth. We shall invoke no god beside Him, for we shall have uttered a blasphemy then. 14 "These our people have taken for worship gods other than Him: why do they not bring forward an authority clear (and convincing) for what they do? Who doth more wrong than such as invent a falsehood against Allah? 15 (They were told), "Now that you have abandoned them and what they worship instead of God, seek refuge in the cave. God will, certainly, grant you mercy and provide you with help to safely get out of this trouble." 16 ۞ And thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend. 17
