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 One (such) way he followed, 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 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 Thereafter he followed a way. 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Then followed he (another) way, 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 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 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 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 ۞ 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 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
