They will ask thee of Dhu'l-Qarneyn. Say: I shall recite unto you a remembrance 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 very limits where the sun sets, he saw it setting in dark turbid waters; and nearby he met a people. We said: "O Dhu al-Qarnayn, you have the power to punish or to treat them with kindness." 86 He said: As for him who doeth wrong, we shall punish him, and then he will be brought back unto his Lord, Who will punish him with awful punishment! 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 Till he reached the point of the rising sun, and saw it rise over a people for whom We had provided no shelter against it. 90 Even so! and We had a full knowledge of what he had. 91 Then he followed (another) way, 92 until, when he reached between the two barriers, he found this side of them a people scarcely able to understand speech. 93 They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?" 94 He said, “That which my Lord has given me control over is better, therefore help me with strength – I shall set up a barrier between you and 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 So they were unable either to scale it or pierce it. 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 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 And We shall present Hell that day for Unbelievers to see, all spread out,- 100 Whose eyes were veiled against My warning, and they could not hear. 101
