And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 With these he traveled 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 But as for him who believes, and does righteousness, he shall receive as recompense the reward most fair, and we shall speak to him, of our command, easiness.' 88 Then he followed yet another path, 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 Thus. And We had encompassed [all] that he had in knowledge. 91 He again pursued a purpose. 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 Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 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 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 dust; and the promise of my Lord is 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 We will fully expose the view of hell on that Day to the disbelievers, 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
