They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 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 He therefore pursued a purpose. 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 answered: "As for him who does wrong [unto others] - him shall we, in time, cause to suffer; and thereupon he shall be referred to his Sustainer, and He will cause him to suffer with unnameable suffering. 87 “And regarding one who believed and did good deeds – so his reward is goodness; and we shall soon give him an easy command.” 88 Then he followed a way 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 He again pursued a purpose. 92 until when he reached a place between the two mountains, he found beside the mountains a people who scarcely understood anything. 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 "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 So they were not able to scale it nor could they make a hole in it. 97 and he said, "This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will level it to dust. My Lord's promise is ever 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 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
