They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We established him in the land, and gave him the means to achieve all things. 84 So he followed a course. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Then he followed the road, 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 Then he followed still another path, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and them. 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 97 [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord 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 We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
