They ask you about Dhu'l-Qarnain. 83 We granted him power in the land and endowed him with all kinds of resources. 84 And he followed a road 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 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 Thereafter he followed a way. 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So, We encompassed in knowledge what was with him. 91 Then he followed still another path, 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 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 Thus they were not able to mount it, nor were they able to burrow through it. 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 ۞ And on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
