And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a way. 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. 87 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 He then followed (another) road 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 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 Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might 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 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 97 [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true." 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 On that day we shall present hell to the disbelievers, plain to view, 100 Whose eyes were veiled against My warning, and they could not hear. 101
