They will ask you about ThulKarnain (the pious and chosen). Say: 'I will recite to you something of his story. 83 We established him in the land and gave him means to all things. 84 With these he traveled 85 Until when he reached the setting-place of the sun, he perceived it setting in a miry spring, and he found beside it a nation. We said: Zul Qarnian! either chastise them or take in respect of them the way of 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 Then he followed yet another path, 89 until he came to the rising-place of the sun, where he found it rising on a people for whom We had provided no shelter from it. 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 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said, 'O Dhool Karnain, behold, Gog and Magog are doing corruption in the earth; so shall we assign to thee a tribute, against thy setting up a barrier between us and between them?' 94 He replied, "The power that my Lord has granted me is better (than your tax). Help me with your man-power and I shall construct a barrier between you and Gog and Magog. 95 Bring me blocks of iron; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce it. 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ And on that day We will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 99 Then We shall bring Hell right before the infidels 100 They whose eyes were under a cover from My reminder and they could not even hear. 101
