They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Indeed We established him upon the earth, and We gave him to everything a way. 84 Then he followed a way. 85 until when he reached the very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to 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 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 He then followed (another) road 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 Thus indeed it was. We had full knowledge of him. 91 Then followed he (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 Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 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 ingots of iron' After he had leveled between the two cliffs, he said: 'Blow' And when he made it a fire, he said: 'Bring me molten copper so that I may pour over it' 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 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 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 on that Day We shall place hell, for all to see, before those who denied the truth 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
