They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Lo! We made him strong in the land and gave him unto every thing a road. 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, "We shall certainly punish him who does wrong; then he shall be brought back to his Lord who will punish him with a grievous punishment, 87 But as for him who believes and does righteous deeds - he will have the ultimate good [of the life to come] as his reward; and [as for us,] we shall make binding on him [only] that which is easy to fulfill." 88 Then he set out on another expedition 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 It was so, for We were fully informed about him. 91 Then he followed the road, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 93 They said, “O Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He said, "What My Lord has given me is better [than any tribute]. Help me with a force of labourers and I will erect a barrier between you and them: 95 Bring me ingots of iron," (which they did) until the space between two mountain sides was filled up. "Blow your bellows," he said; (and they blew) until it was red hot. "Bring me molten brass," he said, "that I may pour over it." 96 So Gog and Magog were unable to pass over it, nor were they able [to effect] in it any penetration. 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 will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
