And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Verily, We established him in the earth, and We gave him the means of everything. 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 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 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 followed a way 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 So it is; and Our knowledge encompasses all that he possessed. 91 Then he followed a way 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them 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 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 Thus were they made powerless to scale it or to dig through 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 let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
