Salama ibn al-Akwa' reported that the Prophet, may Allah bless
him and grant him peace, said, "As for your sacrifices, none of you should
have any of it left in his house after a period of three days. When the
following year came, they aid, 'Messenger of Allah, should we do the same
as we did last year?' He said, 'Eat and store up, That was a year in which
we were in difficulty and I wanted you to help."
