They said to him -through interpreters-: O you Zul- Qarnain, the tribes of Gog and Magog* are people who have both mischief and ill-will in their composition and they spread discord in the land. May we apportion to you a tribute in payment of raising a rampart between us, a rampart that would be invincible against all assaults

*69) As has already been pointed out in E.N. 62, Gog and Magog were the wild tribes of North Eastern Asia which, from the very early times had been making inroads on settled kingdoms and empires in Asia and Europe and ravaging them. According to Genesis (Chapter 10), they were the descendants of Japheth, the sort of Noah, and the Muslim historians have also accepted this. And according to the book of Ezekiel (Chapters 38, 39), they inhabited the territories of Meshech (Moscow) and Tubal (Tubalsek). According to the Israelite historian Josephus, they were the Scythians and their territory spread to the north and the east of the Black Sea. According to Jerome, Magog inhabited the territory to the north of Caucasia near the Caspian Sea.
