Overview
Ya'juj and Ma'juj are two vast nations confined behind a barrier built by Dhul-Qarnayn, as described in Surah Al-Kahf (18:93-99). Near the end of times, after the defeat of the Dajjal, Allah will release them and they will swarm from every elevation, consuming everything in their path. No army will have the power to fight them.
Primary Hadith
Scholarly Context
The Quran mentions Ya'juj and Ma'juj in two surahs — Al-Kahf (18:93-99) describing the barrier, and Al-Anbiya (21:96-97) describing their release as a sign of the Hour. The hadith in Sahih Muslim from An-Nawwas ibn Sam'an provides the most detailed chronological account. Scholars note that their exact identity and location remain from the knowledge of the unseen (ilm al-ghayb), though many classical scholars placed them in Central or East Asia.
