(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 One (such) way he followed, 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern 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 a way 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 So; and We encompassed in knowledge what was with 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 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: That in which my Lord has established me is better, therefore you only help me with workers, I will make a fortified barrier between you and them; 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 they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 On that Day We shall present Gehenna (Hell) to the unbelievers, 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
