From Sahih Muslim (Hadith 7390):
Anas b. Malik reported that Allah's Messenger (ﷺ) said:There will be no land which would not be covered by the Dajjal but Mecca and Medina, and there would no passage out of the passages leading to them which would not be guarded by angels arranged in rows. Then he (the Dajjal) would appear in a barren place adjacent to Medina and it would rock three times that every unbeliever and hypocrite would get out of it towards him
