It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) once supplicated, saying: O Allah! Bless the people of Madinah in their Madinah, and grant blessing in their Sa’ and Mudd. O Allah! Ibrahim was Your servant and friend, and I am Your servant and Messenger. Ibrahim supplicated to You for the people of Makkah; I am supplicating to You for the people of Madinah with the same supplication as Ibrahim made for the people of Makkah, and even more than that. Then he said: Madinah is surrounded by the nets of angels; at every entrance there are two angels appointed for its protection. Neither plague nor Dajjal can enter it. Whoever intends evil against it, Allah will melt him as salt melts in water.
