And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 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 the road, 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 thus [We had made them, and thus he left them; and We did encompass with Our knowledge all that he had in mind 91 Then he followed a road 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 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 ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to 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 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
