We tell you this story for a genuine purpose. They were young people who believed in their Lord and We gave them further guidance. 13 And We made their hearts firm and strong (with the light of Faith in Allah and bestowed upon them patience to bear the separation of their kith and kin and dwellings, etc.) when they stood up and said: "Our Lord is the Lord of the heavens and the earth, never shall we call upon any ilah (god) other than Him; if we did, we should indeed have uttered an enormity in disbelief. 14 These people of ours have taken to worshipping [other] deities instead of Him, without being able to adduce any reasonable evidence in support of their beliefs; and who could be more wicked than he who invents a lie about God? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your [outward] condition - with all that your souls may need! 16 ۞ And [for many a year] thou might have seen the sun, on its rising, incline away from their cave on the right, and on its setting, turn aside from them on the left, while they lived on in that spacious chamber, [bearing witness to] this of God's messages: He whom God guides, he alone has found the right way; whereas for him whom He lets go astray thou canst never find any protector who would point out the right way. 17
