They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of 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 "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 Then he followed yet another path, 89 Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom. 90 So; and We encompassed in knowledge what was with him. 91 Then he followed a way 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and 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," (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 Such was the rampart that Gog and Magog could not scale, nor could they 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 Gehenna (Hell) to the unbelievers, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
