They ask you about Dhu'l-Qarnain. 83 We established him in the land, and gave him the means to achieve all things. 84 He therefore pursued a purpose. 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 He travelled again 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 And once again he chose the right means [to achieve a right end]. 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set 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 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 So they were unable either to scale it or pierce it. 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's promise always comes true." 98 ۞ And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
