Q: What should I do with the meat from the Udhiyyah?
A: It is recommended that the meat be divided into three parts; a part to be gifted, a part to be given as charity, and a part to be consumed. This is also the case for the animal offered on behalf of someone else.
It is permissible to consume most of the animal but not all of it. It is not required for the one who slaughters it to eat it. They can gift that portion.
The gift can be given to a non-Muslim so long as it is not an obligatory Udhiyyah.
If the entire animal is consumed or gifted, the portion dedicated to charity must be made up.
