They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 We established him in the land and gave him means to all things. 84 He therefore pursued a purpose. 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to treat them with kindness." 86 He replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 “And regarding one who believed and did good deeds – so his reward is goodness; and we shall soon give him an easy command.” 88 Thereafter he followed a way. 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed the road, 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), a people who scarcely understood a word. 93 They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 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 ingots of iron' After he had leveled between the two cliffs, he said: 'Blow' And when he made it a fire, he said: 'Bring me molten copper so that I may pour over it' 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of dust; and the promise of my Lord is true." 98 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 and upon that day We shall present Gehenna to the unbelievers 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
