Yahya related to me from Malik from Nuaym ibn Abdullah al-Mujmir that Abu Hurayra said, "The Messenger of Allah ﷺ said, 'There are angels at the entries of Madina, and neither plague nor the Dajjal will enter it.' "
أَنَّهُ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ عَلَى أَنْقَابِ الْمَدِينَةِ مَلاَئِكَةٌ لاَ يَدْخُلُهَا الطَّاعُونُ وَلاَ الدَّجَّالُ
