They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 We established him in the land and gave him means to all things. 84 So he followed a course. 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed a way 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So; and We encompassed in knowledge what was with him. 91 Then he followed still another path, 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 Thus were they made powerless to scale it or to dig through it. 97 He said, 'This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will make it into powder; and my Lord's promise is ever 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 We will bring forth hell, exposed to view, on that day before the unbelievers. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
