They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 With these he traveled 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 him (a disbeliever in the Oneness of Allah) who does wrong, we shall punish him; and then he will be brought back unto his Lord; Who will punish him with a terrible torment (Hell). 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 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 Thus indeed it was. We had full knowledge of him. 91 Then he followed a way 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 Zulqarnain! surely Gog and Magog make mischief in the land. Shall we then pay you a tribute on condition that you should raise a barrier between us and them 94 He said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 So they were unable either to scale it or pierce 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 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
