And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 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 who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 Thereafter he followed a way. 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 [And he marched on] till, when he reached [a place] between the two mountain-barriers, he found beneath 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 said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is true.” 98 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
