The Prophetic mudd vessel represents the measure used by the Prophet (Allah bless him and grant him peace) and the people of Medina. It was used to measure grains as well as the amount of water used for ablutions and bathing.
The scholarly tradition of Islam has preserved and transmitted the mudd, with each generation passing it on to the following through a preserved and written chain of transmission.
The Prophet (Allah bless him and grant him peace) asked Allah to place Divine blessing (barakah) for those who use the mudd. This prayer makes clear that use of Prophetic Mudd fulfils a sunnah that carries Divine blessing.
Abu Hurayra said: ‘When the people would see the first fruit of the harvest, they would bring it to the Messenger of Allah (Allah bless him and grant him peace), who would take it and say: “O Allah, bless us in our fruits, bless us in our city and bless us in our measures of sa’ and mudd. O Allah, verily Ibrahim is Your slave, Your intimate friend and prophet, as I am Your slave and prophet. He beseeched You for Makkah, and I beseech twofold the like thereof for Madina.” He (Allah bless him and grant him peace) would then call the youngest child present and give them the fruit.’
