Hadith 11:145
'Isa ibn Yunus narrated to us, from Abu Bakr, from Abu al-Zahiriyah, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The stronghold of the Muslims during the great battles (al-malahim) is Damascus. Their stronghold against the Dajjal is Bayt al-Maqdis (Jerusalem). And their stronghold against Gog and Magog is Mount Tur."
حدثنا عيسى بن يونس عن أبي بكر عن أبي الزاهرية قال قال رسول الله صلى الله عليه وسلم معقل المسلمين من الملاحم دمشق ومعقلهم من الدجال بيت المقدس ومعقلهم من يأجوج ومأجوج بيت الطور
