The ruling on a single sacrifice on behalf of a group in connected houses, and the theft of a sacrifice

Question : Your Eminence the Shaykh! If there is a group of siblings, but they are in connected houses, each in his own house, does one sacrifice suffice for them? Does it suffice if the youngest of them buys it from his own money? Does it suffice if they are in different cities?

Answer : The criterion in this is that if their food is one. Then one sacrifice suffices, because it is considered one house. As for if each one of them has his own kitchen and his own food, the Sunnah is that each one sacrifices for himself and his family, even if their residence is in the same vicinity, because there are some people whose residential load is in the same vicinity, but each person is independent in his food and drink.
And what the common people call the "qadr," meaning they say the qadr is one, meaning the kitchen is one and the food is one, these are sufficed by one sacrifice. As for if they are separated, each one having his own kitchen and his own food, then each person among them has a sacrifice. As for if they are separated in different lands, even if they are partners in wealth, then it is recommended for each house to have a sacrifice.
