And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 We established him in the land, and gave him the means to achieve all things. 84 He therefore pursued a purpose. 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, 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 (in Allah's Oneness) and works righteousness, he shall have the best reward, (Paradise), and we (Dhul-Qarnain) shall speak unto him mild words (as instructions)." 88 He then followed (another) road 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 This indeed was true. We knew all that he did there. 91 He then followed (another) road 92 Until, when he came between two mountains, he found before them a nation that did not appear to understand any speech. 93 They said: 'O Dhu'l-Qarnain, Gog and Magog are oppressing the land. May we pay you some tribute so that you could build a rampart between us and them?" 94 He said, "That in which my Lord has established me is better [than what you offer], but assist me with strength; I will make between you and them a dam. 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 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 He said, 'This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will make it into powder; and my Lord's promise is ever 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 On that Day We shall lay Hell bare before those who deny the truth, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
