Is a specific sacrifice recommended for someone who lives alone?

Question:
A questioner says: My mother lives alone in a city far from Riyadh, and I will spend the festival of sacrifice with her, if Allah wills, along with my wife and daughter. Is one sacrifice sufficient for me, my family, and my mother, or must each of us have a sacrifice? I am aware that I am able to purchase any number.

Answer:
If your mother is in a house of her own, a sacrifice is recommended for her alone, and you sacrifice for yourself and your household. As long as your mother is independent in her own house, it is better for her to sacrifice if she is able, and you and your household sacrifice. If you move to her place and slaughter the sacrifice there, that is good, if Allah wills.
Q: If he has servants, does he share his sacrifice with them?
A: It is not obligatory. His household: his wife and his children.
Q: Do the servants not count?
A: No, that is a matter of being kind to them, for they are hired workers.
