(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 So he followed a course. 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with kindness." 86 He said, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 Then he followed a way 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So; and We encompassed in knowledge what was with him. 91 Then he followed a way 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said: "O thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 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 Therefore Yajuj and Majuj were neither able to surmount 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 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
