And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 Say: "I will cite before you his commemoration." We gave him authority in the land and means of accomplishing every end. 84 and he followed a way 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 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 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 Then he followed a road 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So (it was). And We knew all concerning him. 91 He again pursued a purpose. 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said: O Dhu'l-Qarneyn! Lo! Gog and Magog are spoiling the land. So may we pay thee tribute on condition that thou set a barrier between us and them? 94 He said: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier 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 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 He said: This is a mercy from my Lord; but when the promise of my Lord cometh to pass, He will lay it low, for the promise of my Lord is true. 98 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
