They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Surely We established him in the land and granted him means of access to every thing. 84 And he followed a road 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: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 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 Then he followed a way 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 It was so, for We were fully informed about him. 91 Then he followed a way 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, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and them.” 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 Such was the rampart that Gog and Magog could not scale, 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 into dust; and the promise of my Lord is true." 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 And We shall bring hell in front of the disbelievers. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
