They ask you about Dhu'l-Qarnain. 83 We established him in the land, and gave him the means to achieve all things. 84 and he followed a way 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with 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 he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He again pursued a purpose. 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 So; and We encompassed in knowledge what was with him. 91 Then he followed (another) course. 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall 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 Thereafter they could neither scale it, 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 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
