Gog and Magog were released when Islam was completed in the 7th Century.

It may be true that Allah completed and finish din (religion) through Muhammad and made Him seal of prophethood, but Baha'u'llah states that this is missing the point. A Most Great Day of Resurrection is mentioned in the Qur'an which coincides with Gog and Magog. Here are some Quran verses that clearly speak of a time after Muhammad. Qur'an: [11:102-7]: ..In that is a Sign for those who fear the penalty of the Hereafter: that is a Day for which mankind will be gathered together: that will be a Day of Testimony. [69:17] : And the angels will be on the sides thereof, and eight will uphold the Throne of thy Lord that day, above them. [50:20] : And the Trumpet shall be blown: that will be the Day whereof Warning (had been given). [39:68-69]: "And there shall be a blast on the Trumpet, and all who are in the Heaven and all who are on the earth shall expire, save those whom God shall vouchsafe to live. Then shall there be another blast on it, and lo! arising they shall gaze around them: and the earth shall shine with the light of her Lord." [7:30]: He will return you (on the Day of Judgment) reverted back to when you were first created. A section guided, and a section will go astray. [43:61] : And (Jesus) shall be a Sign (for the coming of) the Hour (of Judgment: therefore have no doubt about the (Hour), but follow ye Me: this is a Straight Way. [14:48] : "One day the earth will be changed to a different earth, and so will be the heavens, and (men) will be marshalled forth, before Allah, the One, the Irresistible; .." [11:104-7]: "..The day it arrives, no soul shall speak except by His leave: of those (gathered) some will be wretched and some will be blessed. [39:73-4] : "And those who keep their duty to their Lord are driven unto the Garden in troops till, when they reach it, and the gates thereof are opened, and the warders thereof say unto them: Peace be unto you! Ye are good, so enter ye (the Garden of delight), to dwell therein; They say: Praise be to Allah, Who hath fulfilled His promise unto us and hath made us inherit the land* (al-ardh), sojourning in the Garden where we will! So bounteous is the wage of workers." [39:69] : "And the earth shineth with the light of her Lord, and the Book is set up, and the prophets and the witnesses are brought, and it is judged between them with truth, and they are not wronged." Now regarding Gog (Yajuj) and Magog (Majuj) you have the association with Baha'u'llah as follows: "Until when Yajuj and Majuj are conquered and they come swiftly from every elevated place." - Islamic Hadith 1. RUSSIANS: The history of Gog Magog back to the Russians, were in fact Russian tribes which lived in Moscow and other areas in Russia. 2. When we look at the Biblical accounts regarding Gog Magog we can see that they were people who opposed God and his messengers. 3. TURKS:: "Yajuj and Majuj come with wide faces, small eyes, grey hair rushing from every elevated place as if their face are like hammered out shields." (Musnad Ahmad). The hadith describes the Yajuj and Majuj as people whose faces are like hammered shields. The same feature has also been attributed by the prophet to the Turks. Abu Huraira narrates that God"s Apostle said, "The Hour will not be established until you fight with the Turks; people with small eyes, red faces, and flat noses. Their faces will look like shields coated with leather. The Hour will not be established till you fight with people whose shoes are made of hair." Abu Huraira narrates that the Prophet said, "The Hour will not be established till you fight with people wearing shoes made of hair. And the Hour will not be established till you fight with people whose faces look like shields coated with leather. " (Abu Huraira added, "They will be) small-eyed, flat nosed, and their faces will look like shields coated with leather.") The hadith say that the Muslims will fight the Turks and the Yajuj Majuj before the Hour. 4. OPPRESS JESUS: When we look a bit further, we see that one of the characteristics of the Yajuj and Majuj is that they oppose Jesus and his followers. In a long tradition regarding the signs of the Hour, Nawwas Bin Sama"aan says: "".A short period after killing the Dajjal, Jesus will be informed of the release of Ya"juj and Ma"juj. Obeying God"s command He will take the Muslims to Mount Tur for their protection as nobody will be able to kill the Ya"juj Ma"juj. Ya"juj and Ma"juj will come forth from every lofty place causing destruction and bloodshed wherever they go. Their first batch will come to lake Tiberias and drink all of its water. Their last batch will come to it and say, "There was once water in this lake." Thus they will shoot their arrows towards the sky. God will return the arrows covered with blood and these fools will think they have killed those in the heaven. Meanwhile, Jesus and his companions will remain confined until the head of an ox becomes more valuable than 100 gold coins. Jesus and his companions will pray for their destruction. 5. BAHA'U'LLAH: The same thing described above happened to Baha"u"llah and his followers at the hand of the Turkish Ottoman government. Baha"u"llah and his followers were confined to the Prison of Acre in current-day Israel under the Ottoman Empire. Baha"u"llah was confined to this prison by Sultan Abdul Aziz, the head of the Ottoman Empire. In the summer of 1868, Sultan Abdul Aziz issued the following Firman to the governor of Akka: "Mirza Husayn `Ali (Baha"u'llah) and a group of his companions have been sentenced to life imprisonment in the fortress of Akka." On 12 August, 1868, Baha"u"llah, his family and his companions were suddenly surrounded by Ottoman soldiers and marched off to Akka. Baha"u"llah and his followers lived in very harsh conditions in the Prison of Acre. The details mentioned above regarding Baha"u"llah and his followers prove that the Yajuj Majuj were in fact the Ottomans who confined Baha"u"llah and his followers to the Prison of Acre. Baha"u"llah was the return of Jesus foretold in Islam. In a tablet, Baha"u"llah predicted that God would lay hold on "their prince", meaning Sultan Abdul Aziz. The prediction of Baha"u'llah came true, as soon after the revelation of this tablet Sultan Abdul Aziz lost his power and died a very miserable death. The Ottoman Empire also came to an end in the aftermath of World War One. All this fulfils the prophecy contained in the above tradition regarding Jesus praying against the Yajuj and Majuj and the final destruction of the Yajuj Majuj.
