They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 He therefore pursued a purpose. 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of kindness. 86 He said: "I shall punish whosoever is wicked. He will then be sent back to his Lord who will inflict on him a terrible 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 a way 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 So; and We encompassed in knowledge what was with him. 91 He then followed (another) road 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 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 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 He said: 'This is a mercy from my Lord. But when my Lord's promise is come, He will make it dust. The promise of my Lord is true' 98 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 And 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
