They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 And he followed a road 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 said: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 Then he set out on another expedition 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 So, We encompassed in knowledge what was with him. 91 He then followed (another) road 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 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 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 ۞ And on that Day We shall let some of them surge like waves against others, and the Trumpet shall be blown. Then We shall gather 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
