(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 and he followed a way 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them 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 whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then he followed a way 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 Even so! and We had a full knowledge of what he had. 91 Then he followed the road, 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said, "O Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set 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 ingots of iron' After he had leveled between the two cliffs, he said: 'Blow' And when he made it a fire, he said: 'Bring me molten copper so that I may pour over it' 96 So they were unable either to scale it or 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 ۞ 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 And We will present Hell that Day to the Disbelievers, on display - 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
