They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 Lo! We made him strong in the land and gave him unto every thing a road. 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 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 followed he (another) way, 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 Thus indeed it was. We had full knowledge of him. 91 And once again he chose the right means [to achieve a right end]. 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 Zul-Qarnain verily Yajuj and Majuj are working corruption in the land; shall we then pay thee tribute on condition that thou place between us and them a barrier! 94 He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier. 95 Bring me ingots of iron!" Then, after he had [piled up the iron and] filled the gap between the two mountain-sides, he said: "[Light a fire and] ply your bellows!" At length, when he had made it [glow like] fire, he commanded: "Bring me molten copper which I may pour upon 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 ۞ And We shall leave them on that day surging one against other and the trumpet shall be blown, and then We shall assemble them together. 99 And We will bring forth hell, exposed to view, on that day before the unbelievers. 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
