(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 And he followed a road 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of kindness.' 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible punishment. 87 "But as for him who believes (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 Then he followed a road 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 It was so, for We were fully informed about him. 91 He then followed (another) road 92 [And he marched on] till, when he reached [a place] between the two mountain-barriers, he found beneath them a people who could scarcely understand a word [of his language]. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (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 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 And We will present Hell that Day to the Disbelievers, on display - 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
