And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 He travelled on a certain road; 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to 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 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 He travelled again 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 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! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between 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 And (Gog and Magog) were not able to surmount, 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 We shall set hell on that Day unto the infidels with a setting. 100 those whose eyes had been veiled against any remembrance of Me because they could not bear to listen [to the voice of truth]! 101
