And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 He therefore pursued a purpose. 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of kindness. 86 He said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 But as for him who believes and acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 88 Then followed he (another) way, 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between 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; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of dust; and the promise of my Lord is true." 98 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
