They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Verily We! We established him in the earth, and vouchsafed unto him of everything a way. 84 He therefore pursued a purpose. 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 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 yet another path, 89 Until, when he came to the rising place of the sun, he found it rising on a people for whom We (Allah) had provided no shelter against the sun. 90 So (it was). And We knew all concerning him. 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 Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between 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 blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 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. 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 And We shall set hell on that Day unto the infidels with a setting. 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
