And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 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 set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 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 Then he followed a way 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Thereafter 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 Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?" 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; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 On that day we shall present hell to the disbelievers, plain to view, 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
