They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention 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 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 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 him who believes and acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 88 Then he set out on another expedition 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed (another) course. 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 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 replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 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 Thus were they made powerless to scale it or to dig through it. 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 We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 On that day we shall present hell to the disbelievers, plain to view, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
