And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a course. 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness." 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful 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 He travelled again 89 Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom. 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 He then followed (another) road 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, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect 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 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 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of 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 upon that day We shall present Gehenna to the unbelievers 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
