And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Surely We established him in the land and granted him means of access to every thing. 84 So he followed a way. 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible punishment. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 And once again he chose the right means [to achieve a right end]. 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Thereafter he followed a way. 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 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 replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between them. 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 Thus were they made powerless to scale it or to dig through it. 97 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true." 98 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
