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 We made their hearts steadfast when they stood up and said, “Our Lord is the Lord of the heavens and the earth – we shall not worship any other deity except Him – if it were, we have then said something excessive.” 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 "When ye turn away from them and the things they worship other than Allah, betake yourselves to the Cave: Your Lord will shower His mercies on you and disposes of your affair towards comfort and ease." 16 ۞ The sun could be observed to incline away from their cave on the right, as it rose, and to turn away from them on the left, when it set, while they lay in the wide space inside the cave. This is one of the signs of God. He whom God guides is rightly guided; but for him whom He lets go astray, you will find no helper or guide. 17
