[18:83] And they ask you about Zulqarnain. Say: I will recite to you an account of him.
[18:84] Surely We established him in the land and granted him means of access to everything.
[18:85] So he followed a course.
[18:86] 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.
[18:87] He said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement:
[18:88] 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.
[18:89] Then he followed (another) course.
[18:90] Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It;
[18:91] Even so! And We had a full knowledge of what he had.
[18:92] Then he followed (another) course.
[18:93] Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word.
[18:94] They said: O Zulqarnain! Surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them
[18:95] 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;
[18:96] Bring me blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it.
[18:97] So they were not able to scale it nor could they make a hole in it.
[18:98] 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.
[18:99] And on that day We will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together;
[21:95] And it is binding on a town which We destroy that they shall not return.
[21:96] Even when Gog and Magog are let loose and they shall break forth from every elevated place.
[21:97] And the true promise (Qayamah) shall draw nigh, then lo! The eyes of those who disbelieved shall be fixedly open: O woe to us! Surely we were in a state of heedlessness as to this; nay, we were unjust.
