And they ask you about Zulqarnain. Say: I will recite to 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 Then he followed a way. 85 until, when he reached the setting of the sun, he found it setting in a spring of murky water and near it he found some people. We said, "Dhu'l-Qarnayn! You can either punish them or else you can treat them with gentleness." 86 He said: "Whoever doth wrong, him shall we punish; then shall he be sent back to his Lord; and He will punish him with a punishment unheard-of (before). 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 followed he (another) way, 89 Until, when he came to the rising of the sun, he found it rising on a people for whom We had not made against it any shield. 90 Thus indeed it was. We had full knowledge of him. 91 Then he followed a way 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 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 “Give me sheets of iron”; until when he had raised the wall equal to the edge of the two mountains, he said, “Blow”; to the extent that he made it ablaze – he said, “Bring me molten copper to pour upon it.” 96 Thus (Gog and Magog) could neither climb over it nor dig a hole through (the rampart). 97 He said, 'This is a mercy from my Lord. But when the promise of my Lord comes to pass, He will make it into powder; and my Lord's promise is ever 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 Then We shall bring Hell right before the infidels 100 whose eyes were covered against My remembrance, and they were not able to hear. 101
