They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 And he followed a road 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 one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 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 set out on another expedition 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Even so! and We had a full knowledge of what he had. 91 Then he set out on another expedition 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 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 answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 He said: 'This is a mercy from my Lord. But when my Lord's promise is come, He will make it dust. The promise of my Lord is true' 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 And We shall bring hell in front of the disbelievers. 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
