They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 One (such) way he followed, 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness." 86 He said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 He again pursued a purpose. 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed still another path, 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between them. 95 Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 Then We shall bring Hell right before the infidels 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
