They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 He journeyed on a way 85 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He replied, "I shall punish the unjust ones among them and then they will return to their Lord, who will punish them more sternly". 87 But as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 He again pursued a purpose. 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 Thus. And We had encompassed [all] that he had in knowledge. 91 He again pursued a purpose. 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 Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and them?" 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 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 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
