(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 With these he traveled 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 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 as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 Then he followed a way 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Thus. And We had encompassed [all] that he had in knowledge. 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect 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 "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 So they [Gog and Magog] were not able to scale it, nor were they able to bore through 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 On that Day We shall lay Hell bare before those who deny the truth, 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
