And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 He set out (westwards) on an expedition, 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 Then he followed (another) course. 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 (He left them) as they were: We completely understood what was before him. 91 He then followed (another) road 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 Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them 94 He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 "Bring me blocks of iron." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
