And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 We had given him great power in the land and all kinds of resources. 84 and he followed a way 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 whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He then followed (another) road 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 And once again he chose the right means [to achieve a right end]. 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 al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. 95 Bring me blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 ۞ And on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
