Translation of the verse 94 from Surah Al-Kahf : Number of verses 110 - - page 303 - Part 16.
They said: "O Dhul-Qarnain! Verily! Ya'juj and Ma'juj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?"
They said, "O Dhul-Qarnayn, indeed Gog and Magog are [great] corrupters in the land. So may we assign for you an expenditure that you might make between us and them a barrier?"
(18:94) They said, "O Zul-Qarnain, Gog and Magog *69 spread chaos in this land; should we then pay a tribute to you so that you may build a bulwark between us and them ?"
*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.
