Ibn Jurayj related that Abu'z-Zubayr heard him ask Jabir about
when a man's servant has finished his work and heat (i.e. cooking). Did
the Prophet, may Allah bless him and grant him peace, command that the
servant be invited to eat? "Yes," he replied. If one of you dislikes to
have his servant eat with him, he should give him his food by his own hand.'"
