They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 And he followed a road 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 said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Thereafter he followed a way. 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 So (it was). And We knew all concerning him. 91 Then 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 Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? 94 He replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between 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 were unable either to scale it or 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 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 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
