They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We established him in the land, and We gave him a way to everything; 84 and so he chose the right means [in whatever he did]. 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 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 He travelled again 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 This indeed was true. We knew all that he did there. 91 Then he set out on another expedition 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might 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 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 (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes 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 And We shall set hell on that Day unto the infidels with a setting. 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
