According to the Maharil, the Mitzvah of Hachnosas Orchim is only for rich
and/or Chashuva guest. Having poor people as guest, you are fulfilling
the
Mitzvah of Tzedakah . Avraham Avinu was Mekayam
Mitzvahs Hachnasas
Orchim with the Malachim who didn’t need his food.
According to the Yosef Ometz, the Mitzvah of Hachnasas Kallah is
not
the giving of money to poor
Kallahas but to attend the Chupa/wedding.
