(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 Indeed We gave him authority in the land and bestowed him the means of everything. 84 He therefore pursued a purpose. 85 Until, when he reached the setting of the sun, he found it [as if] setting in a spring of dark mud, and he found near it a people. Allah said, "O Dhul-Qarnayn, either you punish [them] or else adopt among them [a way of] goodness." 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 And as for him who believeth and worketh righteously, unto him shall be a goodly hire, and anon we shall speak unto him of our affair something easy. 88 He travelled again 89 To the extent that when he reached the rising-place of the sun, he found it rising upon a nation for which We had not kept any shelter from it. 90 (He left them) as they were: We completely understood what was before him. 91 Then followed he (another) way, 92 Until when he reached (a place) between the two mountains, he found on that side of them a people who could hardly understand a word. 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 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 sheets of iron" - until, when he had leveled [them] between the two mountain walls, he said, "Blow [with bellows]," until when he had made it [like] fire, he said, "Bring me, that I may pour over it molten copper." 96 Thus were they made powerless to scale it or to dig through it. 97 Said [the King]: "This is a mercy from my Sustainer! Yet when the time appointed by my Sustainer shall come, He will make this [rampart] level with the ground: and my Sustainer's 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 On that Day We shall lay Hell bare before those who deny the truth, 100 who have turned a blind eye to My reminder and a deaf ear to My warning. 101
