(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 So he followed a way 85 Till he reached the point of the setting sun, and saw it set behind a muddy lake, and near it found a people. We said: "O Dhu'l-Qarnain, you may either punish them or treat them with kindness." 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 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 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 (He left them) as they were: We completely understood what was before him. 91 Then he followed (another) way, 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand speech. 93 They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? 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 ingots of iron!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on it.' 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore 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 will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 99 and upon that day We shall present Gehenna to the unbelievers 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
