They will ask you about Dhu'l-Qarnayn. Say, "I will give 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 journeyed on a way 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 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 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 Then he followed a way 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 This indeed was true. We knew all that he did there. 91 Then he followed the road, 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 93 They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and 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 blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 Thus were they made powerless to scale it or to dig through 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 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
