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 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 for worship gods other than Him: why do they not bring forward an authority clear (and convincing) for what they do? Who doth more wrong than such as invent a falsehood against Allah? 15 Hence, now that you have withdrawn from them and from all that they worship instead of God, take refuge in that cave: God will spread His grace over you, and will endow you - whatever your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 thou mightest have seen the sun when it rose move away from their cave to the right, and when it set go past them on the left, and they were in the cleft thereof. That was (one) of the portents of Allah. He whom Allah guideth, he indeed is led aright, and he whom He sendeth astray, for him thou wilt not find a guiding friend. 17
