(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 So he followed a way. 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and nearby he found a nation. 'ThulKarnain' We said, 'you must either punish them or show them kindness' 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 87 As for he who believes and does good works he shall receive a fine reward in recompense and we shall speak to him with a mild command' 88 He travelled again 89 Until when he reached the rising place of the sun, he perceived it rising upon a nation for whom against it We had not set a veil. 90 Thus indeed it was. We had full knowledge of 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 said: "The ability my Lord has given me is better. So help me with your manual labour; I will build a wall 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 So they [Ya'juj and Ma'juj (Gog and Magog)] were made powerless to scale it or dig through it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's promise always comes true!" 98 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
