(Muhammad), they will ask you about Dhu 'l-Qarnayn. Say, "I shall tell you something about him". 83 We established him in the land, and gave him the means to achieve all things. 84 One (such) way he followed, 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 the evildoer, him we shall chastise, then he shall be returned to his Lord and He shall chastise him with a horrible chastisement. 87 But he who believes and does the right will have an excellent reward, and we shall make things easy for him." 88 He then followed (another) road 89 Until when he reached the land of the rising of the sun, he found it rising on a people to whom We had given no shelter from It; 90 So (it was)! And We knew all about him (Dhul-Qarnain). 91 And once again he chose the right means [to achieve a right end]. 92 Till, when he came between the two mountains, he found upon their hither side a folk that scarce could understand a saying. 93 They said: "O thou Two-Horned One! Behold, Gog and Magog" are spoiling this land. May we, then, pay unto thee a tribute on the understanding that thou wilt erect a barrier between us and them?" 94 He said: That wherein my Lord hath established me is better (than your tribute). Do but help me with strength (of men), I will set between you and them a bank. 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 Therefore Yajuj and Majuj were neither able to surmount it, nor could they pierce 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 will leave a part of them in conflict with another part, and the trumpet will be blown, so We will gather them all together; 99 And We shall bring hell in front of the disbelievers. 100 whose eyes had become blind against My admonition and who were utterly disinclined to hear it. 101
