And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 He set out (westwards) on an expedition, 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 Then he followed a 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 Thus. And We had encompassed [all] that he had in knowledge. 91 He then followed (another) road 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 Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart 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 Thus they were not able to mount it, nor were they able to burrow through it. 97 He said: "This is a mercy from my Lord: But when the promise of my Lord comes to pass, He will make it into dust; and the promise of my Lord is true." 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 Then We shall bring Hell right before the infidels 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
