And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 He set out (westwards) on an expedition, 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: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Then he followed a road 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 90 Even so! and We had a full knowledge of what he had. 91 Then he followed still another path, 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 95 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 Thereafter they could neither scale it, nor could they pierce 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 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
