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

Gog and Magog are two tribes one are the Khazar Turk Tribe and the other are the Vikings or you can say the Norsemen. Vikings came on to the world stage in 750 A.D out of a Cold Isolated place which is now called Norway. They spread all over the Northern and Western Europe and then spread across the whole of Russia in the 8th and 9th centuries. The Rus was the second name of the Vikings residing in Russian Lands. Russian Land has also served as a kingdom of the Tatar Mongols who contain Viking Genes as well. The Khazar Tribe was released a little earlier than the Vikings in the 7th century. Th Khazar empire was established in 640 A.D just ten years after the Death of Prophet Muhammad (s.a.w.w). I can quote you a hadith which gives us a clear indication that they were released in the life time of Prophet Muhammad (s.a.w.w). Narrated Zainab bint Jahsh: That the Prophet 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 come near. An opening has been made in the wall of gog and Magog like this," making a circle with his thumb and index finger. Zainab bint Jahsh said, "O Allah's Apostle! Shall we be destroyed even though there are pious persons among us?" He said, "Yes, when the evil person will increase." Narrated Abu Said Al-Khudri: The Prophet said "The people will continue performing the Hajj and 'Umra to the Ka'ba even after the appearance of gog and Magog." Narrated Shu'ba extra: The Hour (Day of Judgment) will not be established till the Hajj (to the Ka'ba) is abandoned. (Book #26, Hadith #663) Narrated Zainab bint Jahsh: That the Prophet came to her in a state of fear saying, "None has the right to be worshiped but Allah! Woe to the Arabs because of evil that has come near. Today a hole has been made in the wall of gog and Magog as large as this." pointing with two of his fingers making a circle. Zainab said, "I said, 'O Allah's Apostle! Shall we be destroyed though amongst us there are pious people? ' He said, 'Yes, if evil increases." Narrated Um Salama: The Prophet woke up and said, "Glorified be Allah: What great (how many) treasures have been sent down, and what great (how many ) afflictions have been sent down!" Now Let me quote you some hadiths regarding the Turks and the Gog and Magog and you will find similarity between their descriptions and do remember that when I say turks I dont mean all the turks If you read the history of the turks they originate from central asia and northern caucasus region and they were more than 30 different turk tribes in that region and out of those thirty khazars tribe is the one who was the most superior and with a brutal army against whom even the rising power of Muslims were defeated 4 times and Khazars are the main reason why Islam coudnt spread into europe Because The only way to enter europe was through caucasus mountains and khazar kindom was located just north of those mountain ranges if you check out the map. So Arabs had to fight the Khazars in order to enter europe. Here are the hadiths: This hadith describes the turks: You will fight the people who wear shoes which are made of bristle and kill them. The fight against the people with wide shield faces is a sign for the doomsday. The doomsday won't come until you kill the little eyed, red faced, pug nosed, shield faced, thick skinned Turks.."( Bukhari, e's-Sahih, kitabu'l-Cihad/95; Muslim, e's-Sahih, Kitabu'l-Fiten/66, hadith #: 2912; İbn Maja, hadith #: 4097-409 Now this hadith describes the Gog and Magog: "You say that you have no enemy but you will continue to fight (your) enemies until Gog and Magog emerge with wide faces, small eyes, and reddish black hair. They will pour down from every slope as if their faces are like lowered shields." (Ahmad) There is a great similarity between the turks and the Gog and Magog people. The Khazar tribe genes contain genes of Vikings as well. Vikings are the Magog because the words Gog is described as someone coming out of the word Magog meaning the gog tribe will be a product of Magog tribe. So it is an indication that in ancient times these tribes were united and out of them came the khazars who settled in the northern caucasus region and the magog tribe vikings remained where they were all the time ( in norway). When the promise of ALLAH came true (Islam completed) then that Barrier built by Dhul Qarnain built between the caucasus Mountains passage was shattered and the Khazar tribe was set loose and thus they made their empire in 630's AD. Vikings established their empire a little later in 750 AD. Do you know where are these people these days??? The europeans are in majority descendents of Vikings (Norsemen) and the Askhenazi jews who now control Israel and all the world affairs. Europeans were the one who started the crusades against Muslims, Europeans were the ones who colonized all the parts of the world and destroyed the native races like in Australia in America and in Africa. White Americans are european people by origin and they killed millions in Japan through atom bomb. Both the world wars so far have been started by europeans. I think you know it that Gog and Magog will create fasad wherever they go and they will kill and plunder where ever they go. Arent Europeans responsible for all kinds of fasad today??? Some people say the Mongols were the Gog and Magog well I say they were part of them as the Mongols originated from CHINA but they intermingled with the VIKINGS and the Khazars and transformed themselves into ruthless barbarians so its a matter of Genetics here. Today atleast 90 % of the world has become product of Gog and Magog society and all are destined to hell unless those who resist their system will be saved. Here is a clear indication in this hadith about the fact that today's world is more than 90 % a part of Gog and Magog Society: he Messenger of Allah said, "Allah divided mankind into ten parts. Nine tenths constitute Ya'juj and Ma'juj while the remaining one tenth constitutes the rest of mankind." (Abdullah-b-Amr/Fathul-Bari). Hadrat Abu Saeed Khudri narrates that the Messenger of Allah said, "On the Day of Judgement, Allah will tell Adam to pick out the Jahanamis from his progeny. Adam will ask, "O Allah, who are they?" Allah will say,"999 out of 1000 are Jahanamis while the one is a Jannati." On hearing this the Sahaba over taken by fear asked, "Who will the ONE Jannati be?" The Prophet replied, "Do not grieve the 999 will be Yajuj Ma'juj while you will be the one Jannati." (Bukhari/Muslim) Over the last 1000 years the world population has grown so large that it may be possible that the world population in the times before Islam would have been a mere 5% of the population today. Its because the gog and magog people are scattered in the world and they have expanded their race by inter marriages with different people all over the world. Gog and Magog are already here and we need to beware of them.
