Gog and Magog are mentioned twice in the Holy Qurän. In the above verse (No.94) they have been introduced as a mischief maker people in the land, and also in S 21:96 we read:ِ

      ``Until the Gog and Magog are let through (THE BARRIER) and they shall break forth from every hill.''

      The two verses imply that they were a wild, lawless, cruel, and blood-thirsty people; who lived on plunder of other nations, and making trouble for neighbouring people.

      Almost all the commentators have agreed that they were the wild tribes of central ASIA, who made sudden and hostile incursion on settled kingdoms and empires, at various stages of the history. The Chinese Empire built the great wall of China to prevent the invasion and plunder of a group of them who were called the Mongols.

      The Persian Empire has also suffered from them at various time and place. The last of their raid was in the 12th century, leaded by GENGHIS KHAN in which they utterly destroyed many great cities like NISHÄBUR.

      We may conclude that the people of CAUCASIA were those who asked Cyrus in his journey, to build them a barrier to prevent the sudden attack of these wild and cruel people.
