“Has anyone among you eaten
today?” We said: “Some of us have eaten and some of us have not.”
He
said: “Complete the rest of your day (i.e., do not eat for the
rest of
the day), whoever has eaten and whoever has not eaten. And
send word
to the people of the suburbs to complete the rest of their
day.” He
was referring to the people of the suburbs around
Al-Madinah.
