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 gave him means to all things. 84 So he followed a way. 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Thereafter he followed a way. 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 Thus indeed it was. We had full knowledge of him. 91 Then he followed the road, 92 Until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. 93 They said: "O thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me ingots of iron!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on 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 into powder; and my Lord's promise 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 And We shall set hell on that Day unto the infidels with a setting. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
