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 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 our people have taken gods besides Him; why do they not produce any clear authority in their support? Who is then more unjust than he who forges a lie against Allah? 15 And when you forsake them and what they worship save Allah, betake yourselves for refuge to the cave; your Lord will extend to you largely of His mercy and provide for you a profitable course in your affair. 16 ۞ And thou woudst behold the sun when it riseth veering away from their cave on the right, and when it setteth, passing them by on the left, while they were in the spacious part thereof; that is of the signs of Allah. Whomsoever Allah guideth, he indeed is the guided; and whomsoever He sendeth astray, for him thou wilt never find a directing friend. 17
