They will ask you about Dhu'l-Qarnayn. Say, "I will give you an account of him." 83 Behold, We established him securely on earth, and endowed him with [the knowledge of] the right means to achieve anything [that he might set out to achieve]; 84 With these he traveled 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 replied: 'The evildoer we shall punish. Then he shall return to his Lord and He will punish him with a stern punishment. 87 And as for him who believes and does good, he shall have goodly reward, and We will speak to him an easy word of Our command. 88 He travelled again 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So, We encompassed in knowledge what was with him. 91 Then he set out on another expedition 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 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 said, 'That wherein my Lord has established me is better; so aid me forcefully, and I will set up a rampart between you and between them. 95 Bring me ingots of iron." Then after he had filled up the space between the two mountain-sides, he said: "(Light a fire) and ply bellows." When he had made it (red like) fire, he said: "Bring me molten copper which I may pour on it." 96 Such was the rampart that Gog and Magog could not scale, nor could they pierce it. 97 Dhu l-Qarnayn said, "This barrier is a blessing from my Lord but when His promise comes to pass He will level it to the ground; His promise always comes true." 98 ۞ Upon that day We shall leave them surging on one another, and the Trumpet shall be blown, and We shall gather them together, 99 And We shall set hell on that Day unto the infidels with a setting. 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
