And they ask thee of Zul Qarnain. Say thou: I shall recite unto you of him some mention. 83 Lo! We made him strong in the land and gave him unto every thing a road. 84 So he followed a certain road 85 Until when he reached the place where the sun set, he found it going down into a black sea, and found by it a people. We said: O Zulqarnain! either give them a chastisement or do them a benefit. 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 travelled again 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 So (it was)! And We knew all about him (Dhul-Qarnain). 91 He travelled 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand 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, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and them.” 95 "Bring me blocks of iron." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 97 He said, “This is the mercy of my Lord; then when the promise of my Lord arrives, He will blow it to bits; and my Lord’s promise is true.” 98 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 And on that Day We shall place hell, for all to see, before those who denied the truth 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
