And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Surely We established him in the land and granted him means of access to every thing. 84 One (such) way he followed, 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 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 Then he followed a way 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 (He left them) as they were: We completely understood what was before him. 91 He then followed (another) road 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand speech. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is true.” 98 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 Then We shall bring Hell right before the infidels 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
