AND THEY will ask thee about the Two-Horned One. Say: "I will convey unto you something by which he ought to be remembered." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 and so he chose the right means [in whatever he did]. 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 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 followed yet another path, 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 It was so, for We were fully informed about him. 91 Then he followed a way 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall between you and them. 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 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it. 97 He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for 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 and upon that day We shall present Gehenna to the unbelievers 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
