They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We had given him great power in the land and all kinds of resources. 84 With these he traveled 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 answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 But as for him who believes and does righteous deeds - he will have the ultimate good [of the life to come] as his reward; and [as for us,] we shall make binding on him [only] that which is easy to fulfill." 88 Then he followed the road, 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 This indeed was true. We knew all that he did there. 91 Then he followed a road 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word. 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 answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 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 He said: This is a mercy from my Lord, but when the promise of my Lord comes to pass He will make it level with the ground, and the promise of my Lord is ever true. 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
