Primary text

There will be three strongholds for the Muslims. Their stronghold during the Great Slaughter (Malhama Kubra) which occurs near Antioch and Damascus will be there. Their stronghold against the Dajjal (Antichrist) will be in Bayt Al-Maqdis (Jerusalem). Their stronghold against Gog and Magog will be at Mount Sinai (Tur Sina). Furthermore, the encampment of the Muslims during the Great Slaughter will be in Al-Ghouta, adjacent to the city of Damascus, which is one of the best cities of Ash-Sham.
