And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Surely We established him in the land and granted him means of access to every thing. 84 He set out (westwards) on an expedition, 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 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 whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 And once again he chose the right means [to achieve a right end]. 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 It was so, for We were fully informed about him. 91 He then followed (another) road 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand speech. 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 has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 Thus they were not able to mount it, nor were they able to burrow through 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 ۞ And on that day We shall release them in groups surging like waves one after another, and the Trumpet will be blown – so We shall gather them all together. (* Gog and Magog will come out during the time of Eisa (Jesus – when he comes back to earth) and cause great destruction in the land.) 99 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
