They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 We established him in the land, and We gave him a way to everything; 84 So he followed a course. 85 Until, when he reached the setting place of the sun, he found it setting in a spring of black muddy (or hot) water. And he found near it a people. We (Allah) said (by inspiration): "O Dhul-Qarnain! Either you punish them, or treat them with 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 as for one who believes and does righteousness, he will have a reward of Paradise, and we will speak to him from our command with ease." 88 He again pursued a purpose. 89 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 It was so, for We were fully informed about him. 91 Thereafter he followed a way. 92 Till he reached a place between two mountains, and found this side of it a people who understood but little of what was spoken. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 95 Bring me ingots of iron!' Until, when he had made all level between the two cliffs, he said, 'Blow!' Until, when he had made it a fire, he said, 'Bring me, that I may pour molten brass on it.' 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 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 on that day We shall release them in groups surging like waves one after another, and the Trumpet will be blown – so We shall gather them all together. (* Gog and Magog will come out during the time of Eisa (Jesus – when he comes back to earth) and cause great destruction in the land.) 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 The ones whose eyes were covered from My remembrance, and who could not bear to hear Truth. 101
