They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 So he followed a certain road 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 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 whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 He travelled again 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 So, We encompassed in knowledge what was with him. 91 Then he followed still another path, 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand 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 replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 Thus they were not able to mount it, nor were they able to burrow through 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 on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
