They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance 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 [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 one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He again pursued a purpose. 89 Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed (another) way, 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 al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up 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 Bring me blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through 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 powder; and my Lord's promise is ever true.' 98 ۞ And on that day We shall release them in groups surging like waves one after another, and the Trumpet will be blown – so We shall gather them all together. (* Gog and Magog will come out during the time of Eisa (Jesus – when he comes back to earth) and cause great destruction in the land.) 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
