They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 Verily We established his power on earth, and We gave him the ways and the means to all ends. 84 He set out (westwards) on an expedition, 85 Until, when he reached the setting of the sun, he found it set in a spring of murky water: Near it he found a People: We said: "O Zul-qarnain! (thou hast authority,) either to punish them, or to 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 Then he followed a road 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Thus indeed it was. We had full knowledge of him. 91 Then he followed a way 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 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 Bring me blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
