They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Indeed We gave him authority in the land and bestowed him the means of everything. 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: As to him who is unjust, we will chastise him, then shall he be returned to his Lord, and He will chastise him with an exemplary chastisement: 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 Then followed he (another) way, 89 to the East where he found the sun rising upon a people whom We had exposed to its rays. 90 Even so! and We had a full knowledge of what he had. 91 He then followed (another) road 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 Dhu'l-Qarnayn! Gog and Magog are causing corruption in the land, so may we pay you tribute on condition that you set a barrier between us and 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." At length, when he had filled up the space between the two steep mountain-sides, He said, "Blow (with your bellows)" Then, when he had made it (red) as fire, he said: "Bring me, that I may pour over it, molten lead." 96 So they [Gog and Magog] were not able to scale it, nor were they able to bore through it, 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's promise always comes 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 Unto those whose eyes had been under a covering from My remembrance, nor had they been able to hear. 101
