Is it permissible for a person who vowed an animal for sacrifice (*udhiyah*) to eat from it after slaughtering it?

Primary text

It is permissible for one who vowed an animal for sacrifice (*udhiyah*) in his obligation and then slaughtered it to eat from the sacrificed animal. This is because the vow is understood according to established custom, and the established custom regarding the legislated *udhiyah* involves both slaughtering and eating from it. The vow only serves to obligate the action, not alter the nature of the vowed item. The obligation inherent in the *udhiyah* is distinct from an obligatory sacrificial offering (*hady*) mandated by law from its origin, from which eating is impermissible; the vow is understood in light of the former, not the latter.
