(82) And as for the wall, it belonged to two orphan boys in the city, and there was beneath it a treasure for them, and their father had been righteous. So your Lord intended that they reach maturity and extract their treasure, as a mercy from your Lord. And I did it not of my own accord. That is the interpretation of that about which you could not have patience. (83) And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report. (84) Indeed We established him upon the earth, and We gave him to everything a way. (85) So he followed a way. (86) Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness. (87) He said, "As for one who wrongs, we will punish him. Then he will be returned to his Lord, and He will punish him with a terrible punishment. (88) But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease. (89) Then he followed a way. (90) Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. (91) Thus. And We had encompassed [all] that he had in knowledge. (92) Then he followed a way. (93) Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. (94) They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" (95) He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. (96) 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. (97) So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. (98) [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true.
