The Question About wear the Wall even I dont know that 1, only allaha knows...but may be this might help,
Verse 84 opens with the statement: يَسۡـَٔلُونَكَ (They ask you). Who is asking? Related narratives show that they were the Quraysh of Makkah, those who were coached to ask three questions from the Holy Prophet. The purpose was to test his prophet-hood and veracity. The questions were about Ruh (spirit), Ashab al-Kahf (People of Kahf) and Dhul-Qarnain. Two of these have already been answered. The story of the People of Kahf has appeared earlier in this Surah, 9-26. The question about 'Ruh' has appeared towards the later part of the previous Surah (Bani Isra'il). Who was Dhul-Qarnain and what happened to him? This is the third question. (Al-Bahr al-Muhit)

Dhul-Qarnain: His identity, period and country and the reason why he was so named
Why was he named Dhul-Qarnain? (the one having two horns) Regarding its reason, there are numerous sayings, and strong differences. Some said that he had two curly locks of hair, therefore, he

was called Dhul-Qarnain. Some others said that he ruled countries of the East and West, therefore, he was named Dhul-Qarnain. There was someone who also said that he had marks on his head that resembled those of horns. It appears in some narratives that he had wound marks on both sides of his head, therefore, he was identified as Dhul-Qarnain. Allah knows best. But, this much already stands determined that the Qur’an has certainly not given him the name of Dhul-Qarnain. In fact, this name came from the Jews. He may have been known by this name with them. Whatever part of the event of Dhul-Qarnain has been mentioned by the Holy Qur’an is no more than what is described below:

"He was a righteous and just king who reached the East and the West and conquered countries in between and ruled there justly. All sorts of means had been provided to him by Allah Ta'ala in order to help him achieve his objectives. On the route of his conquests, he traveled in three directions: to the far West, to the far East and then to the mountain range in the North. At the last mentioned place, he closed the pass in between two mountains by a wall cast in molten metal which made it possible for the people of the area to stay protected against the pillage of Gog and Magog."

As for the question posed by the Jews to test the veracity and prophet-hood of the Holy Prophet, the answer given had left them satisfied. They did not ask any more questions, such as: Why was he given the name, Dhul-Qarnain? Which country did he come from? What period of time did he belong to? This tells us that the Jews themselves took such questions to be unnecessary and redundant. And it is obvious that the Qur’an mentions only that part of history or stories which relates to what is beneficial in the present life or in the life to come, or on which depends the understanding of something necessary. Therefore, neither did the Qur’an take these things up nor were there any details about it described in any authentic Hadith. And it was for the same reason that the most righteous forbears of Islam, the Sahabah and the Tabi'in also paid no particular attention to it.

Now the thing that remains to be addressed is this matter of historical narratives or that of the present Torah and Injil. Then it is also evident that perennial interpolations and alterations have not left even the present Torah and 1nj;l intact as revealed Scriptures. Their status can now be that of history at the most. As for ancient historical narratives, they are overwhelmingly filled with Isra'ili tales that come from no authentic source, nor have they been found trustworthy in the sight of the learned of any time. Whatever the commentators have said in this matter is a compendium of these very historical narratives. Therefore, there are countless differences in them. Europeans have given great importance to history in modern times. No doubt, they have carried out painstaking research in this field. Through archaeological excavations and collection of inscriptions and artifacts, they have tried to reach the reality behind past events and in this process, they have come up with achievements not matched in earlier times. But, archaeological finds, inscriptions etc., can certainly help support an event but it is not possible to read a whole event through these. For it, therefore, historical narratives alone have become the basis. As for the validity of old historical narratives in these matters, we have just now learnt that their status is no more than that of a story. In their books, scholars of Tafsir, classical or modern, have reported these narratives in their historical status only no Qur’anic objective depends on the element of their authenticity. Here too, that which is necessary is being written with the same status in view. A comprehensive research relating to this event appears in 'Qasas al-Quran' by Maulana Hifzur-Rahman (RA), re ders with a taste for history may see it there.

In some narratives, it appears that there have been four kings who ruled over the whole world - two believers, and two, disbelievers. The believing kings are:

1) Sayyidna Sulaiman (RA)

2) and Dhul-Qarnain

while the disbelieving ones are Nimrod (Namrud) and Nebuchadnezzar (Bukht Nassar).
By the way Alexander the great as we know in the west is also know as by some as Sikander,,but he was not Dhul-Qarnain....

"Ya'juj and Ma'juj or Gog and Magog are mentioned in the Qur'an in two places in surat al-Kahf 18:94 and in surat al-Anbiya' 21:96. There are several ahadith of the Prophet (peace and blessings be upon him) about them. Gog and Magog are also mentioned in the Bible in the book of Ezekiel chapters 38-39. Some commentators of the Qur'an under the influence of the Bible tried to identify them with the people of Russia and Caucasia, but there is no basis for this neither in the Qur'an nor in the Hadith. We do not need to identify Gog and Magog with any nation or race. It seems that it is a generic name for some wild, unruly, barbaric, uncivilized and un-religious people. They were causing trouble in the past and then again they or some people like them will cause some mischief before the end of the world. It is reported in the ahadith that Imam Mahdi and Jesus (may Allah be pleased with both of them) will destroy them and then peace will prevail on this earth. May Allah protect us from their trials, Ameen."

Elaborating on this, we’d like to cite for you the following:

“Gog and Magog (two tribes or two peoples) will appear at the time of the second coming of Jesus son of Mary (peace be upon him) before the end of the world, soon after the Dajjal (anti-Christ). Almighty Allah will destroy them all in one night, in response to the supplication of Jesus.

Abu Hurayrah (may Allah be pleased with him) reports that the Prophet (peace and blessings be upon him) said: “Every day, Gog and Magog try to dig a way out through the barrier. When they begin to see sunlight through it, the one who is in charge of them says, ‘Go back; you can carry on digging tomorrow,’ and when they come back, the barrier becomes stronger than it was before. This will continue until their time comes and Allah wishes to send them forth. They will dig until they begin to see sunlight, then the one who is in charge of them will say, ‘Go back; you can carry on digging tomorrow, Insha’Allah.’ In this case, he will make an exception by saying Insha’Allah, thus relating the matter to the Will of Allah. They will return on the following day, and find the hole exactly as they left it. They will carry on digging and come out against the people. They will drink all the water, and find the hole exactly as they left it, and the people will entrench themselves in their fortresses. Gog and Magog will fire their arrows into the sky, and they will fall back to earth with something like blood on them. Gog and Magog will say, ‘We have defeated the people of earth, and overcome the people of Heaven.’ Then Allah will send a kind of worm in the napes of their necks, and they will be killed by it... ‘By Him in Whose Hand the soul of Muhammad is, the beasts of the earth will become fat.’” (Reported by At-Tirmidhi, Ibn Majah, and Ahmad)

Gog and Magog were at the time of Dhul-Qarnayn. Dhul-Qarnayn was a good man and a great king. Allah gave him great power, and he ruled the East and West. He held sway over all kings and countries, and traveled far and wide in both East and West. He traveled eastwards until he reached a passage between two hills, through which people were coming out. Those people did not understand anything, because they were so isolated; they were Gog and Magog. They were spreading corruption through the earth, and harming the people, so the people sought help from Dhul-Qarnayn. They asked him to build a barrier between them and Gog and Magog. He sought their help in building it, so together they built a barrier by mixing iron and copper.

Thus Dhul-Qarnayn restrained Gog and Magog behind the barrier. They tried to penetrate the barrier, or to climb over it, but to no avail. They could not succeed because the barrier was so huge and smooth. So they began to dig, and they have been digging for centuries; they will continue to do so until such a time when Allah decrees that they come out. At that time a hole will be made in the barrier, and Gog and Magog will rush out in all directions, spreading corruption, uprooting plants, and killing people. When Jesus (peace be upon him) invoke Allah against them, Allah will send a kind of worm in the napes of their necks, and in the morning they would perish like one single person.”

Based on Ibn Kathir’s Al-Bidayah wa an-Nihayah (The Beginning and the End)

The Qur’an narrates this story saying: “They ask thee concerning Dhul-Qarnayn. Say, I will rehearse to you something of his story.? Verily we established his power on earth, and we gave him the ways and the means to all ends. One (such) way he followed, until, when he reached the setting of the sun, he found it set in a spring of murky water: near it he found a people: we said: O Dhul-Qarnayn (thou hast authority,) either to punish them, or to treat them with kindness. 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). But whoever believes, and works righteousness, he shall have a goodly reward, and easy will be his task as we order it by our command. Then followed he (another) way, until, when he came to the rising of the sun, he found it rising on a people for whom we had provided no covering protection against the sun. (He left them) as they were: we completely understood what was before him. Then followed he (another) way, until, when he reached (a tract) between two mountains, he found, beneath them, a people who scarcely understood a word. They said: O Dhul-Qarnayn the Gog and Magog (people) do great mischief on earth: shall we then render thee tribute in order that thou mightest erect a barrier between us and them? He said: (the power) in which my Lord has established me is better (than tribute): help me therefore with strength (and labor): I will erect a strong barrier between you and them: Bring me blocks of iron. At length, when he had filled up the space between the two steep mountain sides, he said, blow (with your bellows) then, when he had made it (red) as fire, he said: bring me, that I may pour over it, molten lead. Thus were they made powerless to scale it or to dig through it.? He said: this is a mercy from my Lord: but when the promise of my Lord comes to pass, he will make it into dust; and the promise of my Lord is true.” (Al-Kahf: 83-97)

Zaynab bint Jahsh (may Allah be pleased with her) narrates that the Prophet (peace and blessings be upon him) once came to her in a state of fear, and said, “None has the right to be worshipped but Allah. Woe unto the Arabs from a danger that has drawn near. An opening has been made in the dam of Gog and Magog like this,” (making a circle with his thumb and index finger.) Zaynab bint Jahsh said, “O Messenger of Allah! Shall we be destroyed even though there are pious persons among us?” He said, “Yes, when corruption increases.”

Allah Almighty knows best.
