And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 One (such) way he followed, 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: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He again pursued a purpose. 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 90 Even so! and We had a full knowledge of what he had. 91 Then he followed a way 92 Until, when he reached (a tract) between two mountains, he found, beneath them, 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, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 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 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 whose eyes were covered against My remembrance, and they were not able to hear. 101
