They will question thee concerning Dhool Karnain. Say: 'I will recite to you a mention of him. 83 Lo! We made him strong in the land and gave him unto every thing a road. 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 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 as for him who believes and does righteous deeds - he will have the ultimate good [of the life to come] as his reward; and [as for us,] we shall make binding on him [only] that which is easy to fulfill." 88 He travelled again 89 until he reached the limit where the sun rises and he found it rising on a people whom We had provided no shelter from it. 90 So it is; and Our knowledge encompasses all that he possessed. 91 Then he followed a road 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 'ThulKarnain' they said, 'Look, Gog and Magog are corrupting the earth. Build for us a barrier between us and them, and we will pay you a tribute' 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." Then, when he had filled the gap between the mountain sides [he said], "Now blow on the fire with your bellows." When the iron blocks were red with heat, he said, "Bring me molten brass to pour on them." 96 So they were unable either to scale it or 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 ۞ On that Day, We shall let them surge against each other like waves and then the Trumpet will be blown and We shall gather them all together. 99 We will fully expose the view of hell on that Day to the disbelievers, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
