They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 We established him in the land, and gave him the means to achieve all things. 84 Then he followed a way. 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 87 “And regarding one who believed and did good deeds – so his reward is goodness; and we shall soon give him an easy command.” 88 Then he followed (another) course. 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So it is; and Our knowledge encompasses all that he possessed. 91 Thereafter he followed a way. 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and them. 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through 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 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 That will be the Day We shall place Hell before the unbelievers 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
