They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 He therefore pursued a purpose. 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 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 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 set out on another expedition 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 it was. And surely We have encompassed all that was with him in knowledge 91 Then followed he (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 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 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 ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ And on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 On that day we shall present hell to the disbelievers, plain to view, 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
