(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 We established him in the land, and gave him the means to achieve all things. 84 Then he followed a way. 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment! 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 Then he followed (another) course. 89 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; 90 So; and We encompassed in knowledge what was with him. 91 Thereafter he followed a way. 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 Bring me ingots of iron' After he had leveled between the two cliffs, he said: 'Blow' And when he made it a fire, he said: 'Bring me molten copper so that I may pour over it' 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. But when my Lord's promise is come, He will make it dust. The promise of my Lord is 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 blinded to My remembrance and they were not able to hear. 101
