And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We established him in the land, and gave him the means to achieve all things. 84 He therefore pursued a purpose. 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 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed (another) course. 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 Thus indeed it was. We had full knowledge of him. 91 Then he set out on another expedition 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood 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: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier 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 Thereafter they could neither scale it, nor could they pierce it. 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's promise always comes 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 on that Day We shall present Hell to the disbelievers, plain to view, 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
