And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 And he followed a road 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of 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 But as for him who believes and acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 88 Then he followed a way 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 So (it was). And We knew all concerning him. 91 He again pursued a purpose. 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier 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 and he said, "This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will level it to dust. My Lord's promise is ever true!" 98 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
