They ask you about Dhu'l-Qarnain. 83 We granted him power in the land and endowed him with all kinds of resources. 84 And he followed a road 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 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 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 Then he followed another 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 (He left them) as they were: We completely understood what was before him. 91 Thereafter he followed a way. 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce 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 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 And We will present Hell that Day to the Disbelievers, on display - 100 those whose eyes had been veiled against any remembrance of Me because they could not bear to listen [to the voice of truth]! 101
