They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way 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 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 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 He again pursued a purpose. 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So it is; and Our knowledge encompasses all that he possessed. 91 He then followed (another) road 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 93 They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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. But when my Lord's promise is come, He will make it dust. The promise of my Lord is 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 will present Hell that Day to the Disbelievers, on display - 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
