They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 Then 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 to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Then he followed a way 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 Even so! and We had a full knowledge of what he had. 91 Then he followed (another) way, 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 Thus were they made powerless to scale it or to dig through 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 ۞ And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all 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
