They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 We established him in the land, and We gave him a way to everything; 84 So he followed a way. 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with 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 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 Then he followed the road, 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 He travelled 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will 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 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to 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 ۞ 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 And We shall set hell on that Day unto the infidels with a setting. 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
