They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Indeed We established him upon the earth, and We gave him to everything a way. 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 submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed (another) course. 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 Thus it was. And surely We have encompassed all that was with him in knowledge 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 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 in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 Bring me lumps of iron. Then when he had evened up between the two mountain-sides, he said: blow! Then when he had made it fire, he said: bring me and I shall pour thereon molten copper. 96 So they were unable either to scale it or pierce it. 97 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of dust; and 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 upon that day We shall present Gehenna to the unbelievers 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
