(O Muhammad), they ask you about Dhu al-Qarnayn. Say: "I will give you an account of him." 83 Verily, We established him in the earth, and We gave him the means of everything. 84 and he followed a way 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: "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 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 He again pursued a purpose. 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 So, We encompassed in knowledge what was with him. 91 He again pursued a purpose. 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 Zul-Qarnain – indeed Yajuj and Majuj* are spreading chaos in the land – so shall we assign for you a consideration upon the condition that you set up a wall between us and them?” (* Gog and Magog.) 94 He replied: 'That which my Lord has given me is better, therefore help me with all your power, and I will build a barrier between you and between 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 (Thus he constructed the barrier which) neither Gog nor Magog were able to climb nor were they able to dig a tunnel through the iron and brass barrier. 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 ۞ And We will leave them that day surging over each other, and [then] the Horn will be blown, and We will assemble them in [one] assembly. 99 Then We shall bring Hell right before the infidels 100 (To) Those whose eyes had been under a covering from My Reminder (this Quran), and who could not bear to hear (it). 101
