(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 He journeyed on a way 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 He again pursued a purpose. 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-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 And on that Day We shall place hell, for all to see, before those who denied the truth 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
