They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We granted him power in the land and endowed him with all kinds of resources. 84 He therefore pursued a purpose. 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 (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 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 set out on another expedition 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 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then he followed the road, 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 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: 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 ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 So they were not able to scale it nor could they make a hole in 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 dust; and the promise of my Lord is true." 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 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
