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 So 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 who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment! 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 And once again he chose the right means [to achieve a right end]. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then he followed (another) way, 92 until he came between two mountains. He found beside them a people who could scarcely understand a word [of his language]. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He answered: "That wherein my Sustainer has so securely established me is better [than anything that you could give me]; hence, do but help me with [your labour's] strength, [and] I shall erect a rampart between you and them! 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 Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 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 on that Day We shall present Hell to the disbelievers, plain to view, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
