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 chosen (other) gods beside Him though they bring no clear warrant (vouchsafed) to them. And who doth greater wrong than he who inventeth a lie concerning Allah? 15 So, when you have gone apart from them and that they serve, excepting God, take refuge in the Cave, and your Lord will unfold to you of His mercy, and will furnish -- you with a gentle issue of your affair.' 16 ۞ And you might have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the midst of the Cave. That is (one) of the Ayat (proofs, evidences, signs) of Allah. He whom Allah guides, is rightly guided; but he whom He sends astray, for him you will find no Wali (guiding friend) to lead him (to the right Path). 17
