And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 We established him in the land, and We gave him a way to everything; 84 One (such) way he followed, 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness." 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment! 87 But as for him who believes and acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 88 He then followed (another) road 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 So (it was). And We knew all concerning him. 91 He travelled 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: 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 (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 blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 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 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 Then We shall bring Hell right before the infidels 100 Whose eyes were veiled against My warning, and they could not hear. 101
