And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We granted him power in the land and endowed him with all kinds of resources. 84 He travelled on a certain road; 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, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 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 he followed yet another path, 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed still another path, 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said: O Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 94 He said, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and them.” 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 Thus were they made powerless to scale it or to dig through 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 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will 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
