We will relate to thee their tidings truly. They were youths who believed in their Lord, and We increased them in guidance. 13 We strengthened their hearts, when they rose up and declared, "Our Lord is the Lord of the heavens and the earth. Never shall we call upon any deity other than Him: for that would be an outrageous thing to do. 14 Our people have considered other things equal to God. Why cannot they present clear proof in support of their claim. Who is more unjust than one who invents falsehood against God?" 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 [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
