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 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He said, 'As for the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 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 followed he (another) way, 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed a way 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 95 Bring me ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 So they were not able to scale it nor could they make a hole in it. 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is true.” 98 ۞ On that day We shall leave them to surge like waves on one another: the trumpet will be blown, and We shall collect them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
