And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 So he followed a way 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 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 whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed a way 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Even so! and We had a full knowledge of what he had. 91 Thereafter he followed a way. 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said: "O thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 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 [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 Thus were they made powerless to scale it or to dig through it. 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 ۞ 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 On that day we shall present hell to the disbelievers, plain to view, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
