And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We established him in the land, and gave him the means to achieve all things. 84 He journeyed on a way 85 [And he marched westwards] till, when he came to the setting of the sun, it appeared to him that it was setting in a dark, turbid sea; and nearby he found a people [given to every kind of wrongdoing]. We said: "O thou Two-Horned One! Thou mayest either cause [them] to suffer or treat them with kindness!" 86 He replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Then followed he (another) way, 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 It was so, for We were fully informed about him. 91 He again pursued a purpose. 92 [And he marched on] till, when he reached [a place] between the two mountain-barriers, he found beneath them a people who could scarcely understand a word [of his language]. 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 wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 95 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 97 "This is the benevolence of my Lord," he said; "but when the promise of my Lord comes to pass, He will reduce it to a mound of dust; and the promise of my Lord is 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 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 Whose eyes were veiled against My warning, and they could not hear. 101
