They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We established him in the land, and We gave him a way to everything; 84 And he followed a road 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to treat them with kindness." 86 He answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 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 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 So, We encompassed in knowledge what was with him. 91 Then he followed (another) course. 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 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 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 they were not able to scale it nor could they make a hole in it. 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 We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
