And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 He travelled on a certain road; 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to treat them with kindness." 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 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed a road 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 Then he followed still another path, 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up 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 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever 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 upon that day We shall present Gehenna to the unbelievers 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
