Usamah-meaning bin Zaid - told us. Abu "Abdullah al-Qarraz told us that he heard Sa"d bin Malik and Abu Hurairah say:

The Messenger of Allah (ﷺ) said: "O Allah, bless the people of Madinah in their city, bless them in their sa"s, bless them in their mudds [weights and measures].. O Allah, Ibraheem was Your slave and Your close friend (khaleel) and I am Your slave and Messenger. Ibraheem asked you for the people of Makkah and I am asking You for the people of Madinah, as Ibraheem asked You for the people of Makkah, and as much again. Madinah is surrounded by angels; on every route into the city there are two angels guarding it; neither the plague nor the Dajjal wili enter it. Whoever wishes ill to it, Allah will cause him to melt as salt dissolves in water,
