And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 and he followed a way 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to treat them with kindness." 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 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 provided no covering protection against the sun. 90 It was so, for We were fully informed about him. 91 He travelled 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 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 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to pierce it. 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 ۞ 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 present Hell that Day to the Disbelievers, on display - 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
