And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 We had given him great power in the land and all kinds of resources. 84 He set out (westwards) on an expedition, 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He said, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed (another) course. 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 It was so, for We were fully informed about him. 91 Then he followed a way 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 "Bring me blocks of iron." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 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. But when the promise of my Lord comes to pass, He will make it into powder; and my Lord's promise is ever true.' 98 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
