(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 And he followed a road 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible punishment. 87 But as for him who believes and does righteous deeds - he will have the ultimate good [of the life to come] as his reward; and [as for us,] we shall make binding on him [only] that which is easy to fulfill." 88 Then he followed (another) course. 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 So it is; and Our knowledge encompasses all that he possessed. 91 Then he followed a road 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 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 pieces of iron - till, when he had levelled up (the gap) between the cliffs, he said: Blow! - till, when he had made it a fire, he said: Bring me molten copper to pour thereon. 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
