Surah Al-Kahf 18:94

قَالُوا يَا ذَا الْقَرْنَيْنِ إِنَّ يَأْجُوجَ وَمَأْجُوجَ مُفْسِدُونَ فِي الْأَرْضِ

18:94 Yâjûj wa Mâjûj يَأْجُوجَ وَمَأْجُوجَ - Gog and Magog. This is the form in which these names have achieved currency in all European languages (see also Genesis 10.2; 1 Chronicles 1.5; Ezekiel 38.2; 39:5-6). In Ezekiel we read, “Here I am against you, O Gog, chieftain of Meschech and Tubal” (Eze. 38.3; see also Eze 38.2). If we go further to the north of the Caucasus, we find two rivers bearing the names of Tobal and Moskoa, on the latter of which is situated the ancient city of Moscow and on the former, the city of Tobolsk. These two rivers were named after two tribes of Ezek. Josephus, the famous Jewish historian, identifies Gog and Magog with the Scythians. Throughout classical literature, Scythia generally referred to all regions to the north and northeast of the Black Sea. In Târîkh Ibn Khaldûn, Shahnama, and Ghais al-Lughât, Yâjûj and Mâjûj are the people inhabiting lands north of Bactria. From the books of Islamic history, it can be concluded that Gog and Magog were the Gothic tribes who later settled on the southern coasts of the Baltic Sea, they were the ancestors of the present Teutonic and Slavic races, who then migrated into European territories (cf. Târîkh Ibn Khaldûn, Tafsîr Mu‘âlam by Suddî; Qitâdah; Baidzawî).

Based on what has been said, Gog and Magog can refer to the numerous nations located north of Persia, particularly in Russia and Europe - the Christian nations of today. According to the Christian interpreters of the Bible, Gog and Magog were the evil nations who will serve as the forces of Satan at Armageddon. They are also the last two survivors of a mythical race inhabiting Britain (Encyclopedia Britannica). A curious side-note in this context is the gigantic statues of Gog and Magog at the gates of Guild Hall in London, England, which are sometimes referred to as the guardians of the city. It is known that effigies similar to these existed in London as early as the time of Henry V.
