And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 We granted him power in the land and endowed him with all kinds of resources. 84 Then he followed a way. 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 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 Thereafter he followed a way. 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 It was so, for We were fully informed about him. 91 He travelled 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 They said: O Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise 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 blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 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 We will bring forth hell, exposed to view, on that day before the unbelievers. 100 Those whose eyes had been within a cover [removed] from My remembrance, and they were not able to hear. 101
