(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Surely We established him in the land and granted him means of access to every thing. 84 and 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: "We will chastise him who does wrong, whereafter he will be returned to his Lord and He will chastise him grievously. 87 but whoever believes and does good works shall have a good reward and We shall facilitate his matter by Our command." 88 Thereafter he followed a way. 89 until he reached the rising of the sun, he found it rising upon a nation for whom We provided no veil against it to shade them. 90 Thus was the state of those people, and We encompassed in knowledge all concerning Dhu al- Qarnayn. 91 Then he followed a way 92 when he reached between the two barriers he found on one side of them a nation who could barely understand speech. 93 They said, "Dhu 'l-Qarnayn, Gog and Magog are ravaging this land. Would you establish a barrier between us and them if we pay you a certain tax?" 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 blocks of iron to fill up the passage between the two mountains." He told them to ply their bellows until the iron became hot as fire. Then he told them to pour on it molten brass." 96 And (Gog and Magog) were not able to surmount, nor could they pierce (it). 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 ۞ On that day, We will let them surge on one another, and the Horn shall be blown, and We will gather them all together. 99 and upon that day We shall present Gehenna to the unbelievers 100 (Unbelievers) whose eyes had been under a veil from remembrance of Me, and who had been unable even to hear. 101
