They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 So he followed a way 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible punishment. 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 Then he followed a way 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 (He left them) as they were: We completely understood what was before him. 91 Then he followed the road, 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 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, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 He said: This is a mercy from my Lord, but when the promise of my Lord comes to pass He will make it level with the ground, and the promise of my Lord is ever true. 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 and upon that day We shall present Gehenna to the unbelievers 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
