And they ask you regarding Zul-Qarnain; say, “I shall recite his story to you.” 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 He therefore pursued a purpose. 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: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Thereafter he followed a 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 is; and Our knowledge encompasses all that he possessed. 91 And once again he chose the right means [to achieve a right end]. 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said: O Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 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 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 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 [Dhul-Qarnayn] said, "This is a mercy from my Lord; but when the promise of my Lord comes, He will make it level, and ever is the promise of my Lord true." 98 ۞ And on that Day [i.e. the Day Ya'juj and Ma'juj (Gog and Magog) will come out], We shall leave them to surge like waves on one another, and the Trumpet will be blown, and We shall collect them all together. 99 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
