They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 With these he traveled 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of kindness.' 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 He again pursued a purpose. 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 Thus indeed it was. We had full knowledge of him. 91 Then he followed a way 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 said: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 He said: This is a mercy from my Lord, but when the promise of my Lord comes to pass He will make it level with the ground, and the promise of my Lord is ever 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 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
