And they ask you, [O Muhammad], about Dhul-Qarnayn. Say, "I will recite to you about him a report." 83 We established him in the land, and gave him the means to achieve all things. 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 believeth and doeth right, good will be his reward, and We shall speak unto him a mild command. 88 Then he followed another way, 89 Till, when he reached the rising-place of the sun, he found it rising on a people for whom We had appointed no shelter therefrom. 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 Then followed he (another) way, 92 Until, when he reached [a pass] between two mountains, he found beside them a people who could hardly understand [his] speech. 93 They said: "O Zul-qarnain! the Gog and Magog (People) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? 94 He answered: "Whatever my Lord has granted me is good enough. But help me with your labour and I will erect a rampart between you and them. 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 Thus they were not able to mount it, nor were they able to burrow through it. 97 He said: this is a mercy from my Lord; then when the promise of my Lord cometh, He shall make it powder, and the promise of my Lord is ever true. 98 ۞ On the day when the barrier is demolished, We will leave human beings in chaos. We will leave them like the waves of the sea striking against each other. Then the trumpet will be sounded and We will bring them all together. 99 And on that Day We shall present Hell to the disbelievers, plain to view, 100 Those whose eyes were hoodwinked from My reminder, and who could not bear to hear. 101
