And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 He journeyed on a way 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 him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Then he set out on another expedition 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 Even so! and We had a full knowledge of what he had. 91 He then followed (another) 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 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 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." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through 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 ۞ 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 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
