They ask thee concerning Zul-qarnain. Say, "I will rehearse to you something of his story." 83 We granted him power in the land and endowed him with all kinds of resources. 84 So he followed a certain road 85 until, when he reached the setting of the sun, he found it setting in a muddy spring, and he found nearby a people. We said, 'O Dhool Karnain, either thou shalt chastise them, or thou shalt take towards them a way of 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 Then he followed a road 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 Thus it was. And surely We have encompassed all that was with him in knowledge 91 Then he set out on another expedition 92 Until when he arrived between the two mountains, he found beside them a people who well-nigh understood not a word. 93 They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might 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; until when he had filled up the space between the two mountain sides, he said: Blow, until when he had made it (as) fire, he said: Bring me molten brass which I may pour over it. 96 Thus were they made powerless to scale it or to dig through it. 97 Dhu al-Qarnayn said: "This is a mercy from my Lord: but when the time of my Lord's promise shall come, He will level the rampart with the ground. My Lord's promise always comes true." 98 ۞ And on that day we shall let some of them surge against others, and the Trumpet will be blown. Then We shall gather them together in one gathering. 99 And We shall set hell on that Day unto the infidels with a setting. 100 whose eyes were blinded to My remembrance and they were not able to hear. 101
