They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We had given him great power in the land and all kinds of resources. 84 He journeyed on 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 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 set out on another expedition 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed still another path, 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you 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 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 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or 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 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 And We will present Hell that Day to the Disbelievers, on display - 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
