And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Surely We established him in the land and granted him means of access to every thing. 84 One (such) way he followed, 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: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 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 He again pursued a purpose. 89 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. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 He then followed (another) road 92 Until, when he reached between two mountains, he found, before (near) them (those two mountains), 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: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier between you and them: 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon it." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 And on that Day We shall place hell, for all to see, before those who denied the truth 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
