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 So he followed a certain road 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 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 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 Then he followed a way 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 So (it was). And We knew all concerning him. 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 They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?" 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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 Thereafter they could neither scale 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 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
