And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 and he followed 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 said: "As for him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 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 Then he followed (another) course. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 He again pursued a purpose. 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 bring me blocks of iron." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 Such was the rampart that Gog and Magog could not scale, 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 ۞ AND ON that Day" We shall [call forth all mankind and] leave them to surge like waves [that dash] against one another; and the trumpet [of judgment] will be blown, and We shall gather them all together. 99 And We shall set hell on that Day unto the infidels with a setting. 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
