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 He set out (westwards) on an expedition, 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 86 He said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 87 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 Thereafter he followed a way. 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 This indeed was true. We knew all that he did there. 91 Then he followed the road, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. 95 Give me pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise 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 And 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
