They ask you about Dhu'l-Qarnain. 83 Verily, We established him in the earth, and We gave him the means of everything. 84 With these he traveled 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 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 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 He again pursued a purpose. 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 He then followed (another) road 92 [And he marched on] till, when he reached [a place] between the two mountain-barriers, he found beneath them a people who could scarcely understand a word [of his language]. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and them.” 95 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 Thereafter they could neither scale it, nor could they pierce 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 ۞ 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 On that Day We shall lay Hell bare before those who deny the truth, 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
