I have, in the previous articles discussed Yajuj Majuj (Gog and Magog) and their existence. You can refer to that article for background and history. The most important thing now is to know where exactly Yajuj Majuj (Gog and Magog) are located on this earth?
There are many theories and concepts regarding the location. Some people believe that YajujMajuj (Gog and Magog) were not actually imprisoned by Zulqurnain A.S instead the wall which is mentioned in the Holy Quran built by Zulqurnain was merely the wall of Allah’s will which stopped them from invading the world.
01-The Great Wall of China: They are thousands in number and may be Mongols or Chinese. It is said that when other powerful nations will come to an end, Chinese will rise and invade the whole world, eating humans.
Thus the expected location by some of the Kings in previous times was stated to be The Great Wall of China, built by the Chinese King Fagfor, almost about 3460 years after Prophet Adam was born.
But we have heard that according to Islam that particular wall is on the eastern side of the world but Great Chinese Wall is on the north.
02-The North Pole or the South Pole: There are various concepts with respect to Hadith. It was said there is a metal wall behind which Gog Magog are trapped and they try to dig a hole in it every day but fail to complete it.
This indicates that the wall might be covered with dirt, snow or sand. Corrosion is metal’s property called oxidation. Cold temperatures associated with high altitudes or snowy environment stops oxidation.
Many years have passed but YajujMajuj (Gog and Magog) didn’t invade the world means the wall is still strong enough, from which it is extracted that it is some region where there is snow the whole year.
It can be said that it is somewhere in the North Pole and the South Pole where latest technology fails.
03-Under the Surface of Earth: It is said that they have red hairs and small eyes which indicate, they might be underground, as people living in caves or less exposure to sunlight tend to have such appearance.
The metal gate might be the entrance to an underground cave.
04-Siberia or Himalaya: Scholars and historians are still doing research and studies on the location of Gog Magog. Some also say that the wall is not imaginary but real, and it is found to be in Siberia.
Some say the Himalayas might be the correct location. Some suggest that they live in northern areas of Azerbaijan, Armenia, and Georgia.
05-Caspian Sea: On the other hand, it is concluded by some modern scholars that the two Barrier Mountains are the Caucasus mountain range, the eastern and western sections of which is separated by a narrow pass called the Daryal Gorge.
This Caucasus mountain range spreads its origin in the west from the Black Sea to the Caspian Sea in the east.
06-Mongolia and Russia: Some historians even gave maps locating the expected location of YajujMajuj (Gog and Magog) which somewhere denotes it to be between Mongolia and Russia or somewhere near Georgia bordering Turkey.
07-Bukhara and Tirmidhi: A scholar summed that the wall is in central Asia near Bukhara and Tirmidhi and the place is called Derbent.
To sum up it all up, in the end, I would like to say that the exact location is not known or proved by anyone and it remains a mystery.
What I think is that the location might be related somehow to the mysterious Bermuda Triangle. All these are just human interpretations and only Allah the Almighty knows the truth.
