And they ask you about Zulqarnain. Say: I will recite to you an account of him. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 He journeyed on a way 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 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 acts righteously, his will be a goodly reward and we shall enjoin upon him only mild commands." 88 Thereafter he followed a way. 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 So, We encompassed in knowledge what was with him. 91 Then he followed (another) course. 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 thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said: better is that wherein my Lord hath established me; so help me with might, and I shall place between you and them a rampart. 95 Bring me blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 Thus they were not able to mount it, nor were they able to burrow through it. 97 He said: This is a mercy from my Lord, but when the promise of my Lord comes to pass He will make it level with the ground, and the promise of my Lord is ever true. 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
