1,321. Buried at Night or Erev Shabbos

205:5 If the deceased was buried at night and the mourner wants to eat at night, he may not eat of his own food; others should bring food for him. If he doesn't want to eat at night, he may not eat the first daytime meal of his own food. Since day follows night in the Jewish calendar, this is still the first day.

205:6 If the deceased person was buried on a Friday from nine hours of the day and on, this is a time when one is not permitted to sit down to a meal. Therefore, he should not be brought food in order to honor Shabbos. Similarly, the mourner should not eat anything until night.
