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

First of all Khazars were recognized as a force first when The Arabs fought them before that the world just knew about the Khazar people as some tribes of people who live remotely and thus the reality of Khazars was hidden but when Arabs fought them they came to know about the military strength of these people which then made Khazars a recognizable force in the known world then. In the days when Muhammad (s.a.w.w) was alive these people had just besieged the Barrier and they wanted to organize before they start their mischief on earth. The khazar empire was established in the year 640 AD, 8 years after the death of Muhammad (s.a.w.w). There are some Muslims in the past who recognized them as Gog and Magog like Istakhri, Al fadhlan etc. One must understand the logic that Gog and Magog and the Anti-Chtist are the seditions which ALLAH didn't wanted to get recognized by the Humans so early. These two seditions are actually tests of Mankind and its ALLAH's will when He wants these two seditions to be recognized by Humans. ALLAMA Muhammad Iqbal recognized these people for the first time back in 1924 when European people abolished Khilafah and decided to make a Jewish State in an area where the Palestinians were living for centuries. It was an evil and Unjust plan which ALLAMA Iqbal recognized back then and he has mentioned gog and magog in one of his poems : Urdu Version: " Khul Gaye Yajuj Majuj ke Lashkar Tamam" " Chashm e Muslim dekh le tafseer e Harf e Yansilun" English Meaning: "Gog and Magog all have been released" "The Muslim eye will see the meaning of 'Yansilun'" The Word Yansilun refers to the two Verses of Surah Anbiya in the Quran : Verse#95 (Surah Anbiya) وَحَرَامٌ عَلَىٰ قَرْيَةٍ أَهْلَكْنَاهَا أَنَّهُمْ لَا يَرْجِعُونَ "But there is a ban on any population which We have destroyed: that they shall not return," Verse#96 (Surah Anbiya) حَتَّىٰ إِذَا فُتِحَتْ يَأْجُوجُ وَمَأْجُوجُ وَهُمْ مِنْ كُلِّ حَدَبٍ يَنْسِلُونَ The meaning of these have been described in my Argument in the first round. Check it!! One of Allama Iqbal's students "Maulana Fadhal Ur Rehman Ansari" carried out further research on these views of Allama Iqbal and got convinced that these people are released. For some reason Maulana Fadhal ur Rehman Ansari didnt openly preach this topic and his student Maulana Sheikh Imran hosein started his research on this topic in the early 90's and he till date is the only scholar of this era to have made the most comprehensive and logical explanation of these topics and have also concluded that the Khazars are the people of Gog and Magog but yet he didnt mention about the Vikings ( Norsemen). The vikings theory is researched by his students of which one of them is me. I am pretty convinced now that The Norsemen (vikings) were the Magog and Khazars are Gog. You can view the history of Khazars and the vikings and you will get an idea when they came on the world stage and they came like waves as well. First came the Khazars, then Vikings, then Mongols, then Rothschilds emerged in the 17th century and are ruling the world currently from behind their puppets sitting on top of almost all the Govts of this world today. Khazars, Vikings, Mongols, and the Rothschilds all have the same blood Genes. The white people of Europe originated from Germanic tribes in Ancient times out of which came the tribes of Vikings Later on and Khazars came out of the turk Tribes of central Asia. One thing to note here is that turks and the Germanic Tribes are both from the children of Japheth the third son of Noah(a.s) and Bible's description states that gog and magog will be from the Third son of Naoh (Japheth). Is this a coincidence?? I dont think so!!
