They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance of him. 83 We established him in the land and gave him means to all things. 84 One (such) way he followed, 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: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He travelled again 89 until, when he reached the rising of the sun, he found it rising upon a people for whom We had not appointed any veil to shade them from it. 90 This indeed was true. We knew all that he did there. 91 He travelled 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 – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. 95 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's 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 Then We shall bring Hell right before the infidels 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
