And they ask you about Dhul-Qarnain. Say: "I shall recite to you something of his story." 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 With these he traveled 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of kindness.' 86 He replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 But as for him who believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Then he followed another way, 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 It was so, for We were fully informed about him. 91 Then followed he (another) 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, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 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 "Give me pieces (blocks) of iron," then, when he had filled up the gap between the two mountain-cliffs, he said: "Blow," till when he had made it (red as) fire, he said: "Bring me molten copper to pour over it." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 He said: 'This is a mercy from my Lord. But when my Lord's promise is come, He will make it dust. The promise of my Lord is 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 On that day we shall present hell to the disbelievers, plain to view, 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
