And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 So he followed a way. 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 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 he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed the road, 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 He again pursued a purpose. 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 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 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true." 98 ۞ AND ON that Day" We shall [call forth all mankind and] leave them to surge like waves [that dash] against one another; and the trumpet [of judgment] will be blown, and We shall gather them all together. 99 And We shall set hell on that Day unto the infidels with a setting. 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
