They ask you about Dhu'l-Qarnain. 83 Verily, We established him in the earth, and We gave him the means of everything. 84 So he followed a certain road 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 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 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 Then followed he (another) way, 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 90 This indeed was true. We knew all that he did there. 91 Then he followed still another path, 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 Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 ۞ 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 on that Day We shall present Hell to the disbelievers, plain to view, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
