Is it obligatory to take money from the bank belonging to an orphaned girl with mental disabilities to perform the Udhiyah on her behalf, or else would that incur sin?

Scholars have differed regarding offering a sacrifice on behalf of an orphan or a mentally incapacitated person from their own wealth. Some have permitted it if the orphan is wealthy and will not be harmed by the expenditure, or if the orphan comprehends the sacrifice and rejoices in it, provided that meat is supplied to him and not given away as charity. Others have prohibited it, considering the sacrifice to be a voluntary donation that is not permissible with the orphan's money. In summary, no sacrifice should be offered on behalf of a mentally challenged orphan, as the sacrifice provides no benefit to him, and because the meat is usually given away as charity, which is not permissible with the orphan's money.
