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 So he followed a course. 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 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He then followed (another) road 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So (it was). And We knew all concerning him. 91 Then he followed (another) course. 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He answered: "That wherein my Sustainer has so securely established me is better [than anything that you could give me]; hence, do but help me with [your labour's] strength, [and] I shall erect a rampart between you and them! 95 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever 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 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
