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 to the West where he found the sun setting into a warm source (spring) of water and a people living near by. We asked him, "Dhu 'l-Qarnayn, you may punish them or treat them with kindness?" 86 He said: as for him who doeth wrong, presently we shall torment him, and thereafter he shall be brought back to his Lord, and He shall torment him with a torment formidable. 87 But as for him who believes, and does righteousness, he shall receive as recompense the reward most fair, and we shall speak to him, of our command, easiness.' 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. And We had encompassed [all] that he had in knowledge. 91 Then he followed a way 92 after this to the middle of two mountains where he found a people who could hardly understand a single word. 93 They said: "O Dhu al-Qarnayn, Gog and Magog are spreading corruption in this land. So shall we pay you taxes on the understanding that you will set up a barrier between us and them?" 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' 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 Thus they were not able to mount it, nor were they able to burrow through 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 ۞ 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 will present Hell that Day to the Disbelievers, on display - 100 whose eyes had been veiled against Our Quran and who were not able to hear (its recitation). 101
