We narrate unto you (O Muhammad SAW) their story with truth: Truly! They were young men who believed in their Lord (Allah), and We increased them in guidance. 13 and endowed their hearts with strength, so that they stood up and said [to one another]: "Our Sustainer is the Sustainer of the heavens and the earth. Never shall we invoke any deity other than Him: [if we did,] we should indeed have uttered an enormity! 14 These our people have taken to them other gods, apart from Him. Ah, if only they would bring some clear authority regarding them! But who does greater evil than he who forges against God a lie? 15 [The youths said to one another], "And when you have withdrawn from them and that which they worship other than Allah, retreat to the cave. Your Lord will spread out for you of His mercy and will prepare for you from your affair facility." 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
