They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 So he followed a way 85 Till, when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a people thereabout. We said: O Dhu'l-Qarneyn! Either punish or show them kindness. 86 He said: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 "But whoever believes, and works righteousness,- he shall have a goodly reward, and easy will be his task as We order it by our Command." 88 He again pursued a purpose. 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had provided no covering protection against the sun. 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then followed he (another) way, 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 Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 94 He said: "(The power) in which my Lord has established me is better (than tribute): Help me therefore with strength (and labour): I will erect a strong barrier between you and them: 95 Bring me lumps of iron. Then when he had evened up between the two mountain-sides, he said: blow! Then when he had made it fire, he said: bring me and I shall pour thereon molten copper. 96 Such was the rampart that Gog and Magog could not scale, nor could they 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 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 And We shall set hell on that Day unto the infidels with a setting. 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
