The Prophet ﷺ said, "The terror of the false Messiah, the Dajjal, will not enter Madinah. On that day it will have seven gates, with two angels guarding each gate."
عن النبي ﷺ قال: لا يدخل المدينة رعب المسيح الدجال، لها يومئذ سبعة أبواب، على كل باب ملكان.
Bukhari narrated it in the Virtues of Madinah (1879), from Abdul-Aziz bin Abdullah, who said, Ibrahim bin Saad narrated to me, from his father, from his grandfather, from Abu Bakra, and he mentioned it.
