They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 He journeyed on a way 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 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 "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 set out on another expedition 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed (another) way, 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 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 Bring me ingots of iron!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on it.' 96 Thus were they made powerless to scale it or to dig through it. 97 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord 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 will present Hell that Day to the Disbelievers, on display - 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
