They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 With these he traveled 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 the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 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 He then followed (another) road 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Then he followed the road, 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any 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 said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 Thereafter they could neither scale it, nor could they pierce 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 let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
