It was
narrated that ‘Aishah said:
“The Messenger of Allah (ﷺ)
entered
the house and saw a piece of bread that had been thrown (on
the
floor). He picked it up, wiped it and ate it, and said: ‘O
‘Aishah,
show honor to the precious (i.e., food), for is the blessing
of food
departs from people, it never comes back.’”
