And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 We established him in the land, and gave him the means to achieve all things. 84 So he followed a course. 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 As for those who believe and do good, they will receive virtuous rewards and We will tell them to do only what they can. 88 Then he followed yet another path, 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Even so! and We had a full knowledge of what he had. 91 He travelled 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, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 95 Bring me blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes 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 On that day we shall present hell to the disbelievers, plain to view, 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
