They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We had given him great power in the land and all kinds of resources. 84 One (such) way he followed, 85 To the extent that when he reached the setting-place of the sun, he found it setting in a muddy spring, and found a nation there; We said, “O Zul-Qarnain – either punish them or choose kindness for them.” 86 He submitted, “Regarding one who has done injustice, we shall soon punish him – he will then be brought back to his Lord, Who will punish him severely.” 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then he followed a way 89 [And then he marched eastwards] till, when he came to the rising of the sun he found that it was rising on a people for whom We had provided no coverings against it: 90 Thus it was. And surely We have encompassed all that was with him in knowledge 91 He then followed (another) road 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 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 to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 Thus were they made powerless to scale it or to dig through it. 97 Dhul-Qarnain) said: "This is a mercy from my Lord, but when the Promise of my Lord comes, He shall level it down to the ground. And the Promise of my Lord is ever true." 98 ۞ We shall leave them on that day surging like waves pressing one against the other, and the trumpet blast will be sounded, when We shall gather them all together. 99 And We shall set hell on that Day unto the infidels with a setting. 100 Whose eyes were veiled against My warning, and they could not hear. 101
