And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We granted him power in the land and endowed him with all kinds of resources. 84 and so he chose the right means [in whatever he did]. 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 86 He said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 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 the road, 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 about him (Dhul-Qarnain). 91 Then he followed a way 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 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 said: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier between you and them: 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 Thus they were not able to mount it, nor were they able to burrow through it. 97 [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true." 98 ۞ And on that day We shall release them in groups surging like waves one after another, and the Trumpet will be blown – so We shall gather them all together. (* Gog and Magog will come out during the time of Eisa (Jesus – when he comes back to earth) and cause great destruction in the land.) 99 and upon that day We shall present Gehenna to the unbelievers 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
