And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Surely We established him in the land and granted him means of access to every thing. 84 And he followed a road 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 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 another way, 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 it was. And surely We have encompassed all that was with him in knowledge 91 Then he followed (another) course. 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand speech. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 Thus they were not able to mount it, nor were they able to burrow through 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 We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
