They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 We had given him great power in the land and all kinds of resources. 84 He journeyed on a way 85 Till he reached the point of the setting sun, and saw it set behind a muddy lake, and near it found a people. We said: "O Dhu'l-Qarnain, you may either punish them or treat them with kindness." 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 And once again he chose the right means [to achieve a right end]. 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 So; and We encompassed in knowledge what was with him. 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, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 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 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 my Lord's promise is come, He will make it dust. The promise of my Lord is true' 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
