(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Surely We established him in the land and granted him means of access to every thing. 84 He journeyed on a way 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of 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 regarding one who believed and did good deeds – so his reward is goodness; and we shall soon give him an easy command.” 88 He then followed (another) road 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 (He left them) as they were: We completely understood what was before him. 91 Then he set out on another expedition 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] 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: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 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 And thus [the rampart was built, and] their enemies were unable to scale it, and neither were they able to 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 bring hell in front of the disbelievers. 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
