Is it permissible to eat from the sacrifice of a vow?

Question : Is what is obligatory by vow like what is obligatory by the Shari'ah?

Answer : Yes, there is a difference of opinion, as the author stated. This leads to several issues. The first issue is eating from the sacrifice of a vow, and there are two views on this. Abu Bakr al-Jawhari chose one of them, and this is its description. This is because the one who makes the vow says, "I have a vow upon me to Allah to slaughter a sacrifice." It is well known that the sacrifice, by its condition, is something from which one does not eat. There are two ways to phrase the vow of sacrifice: the first is to say, "I have a vow upon me to Allah to offer a sacrifice this year," and the second is to say, "I have a vow upon me to Allah to offer a sacrifice of this type." Both are the same. The correct view is that he may eat from it, because the subject of the sacrifice in the Shari'ah is what? Eating, giving, and charity.
