They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 We had given him great power in the land and all kinds of resources. 84 He travelled on a certain road; 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 He again pursued a purpose. 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 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 On that day we shall present hell to the disbelievers, plain to view, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
