What is the difference between an Udhiyah and a Hady, and where is it permissible to slaughter each of them and for whom are they slaughtered?

The jurists have mentioned several differences between the Hady (sacrificial animal offered during Hajj) and the Udhiyah (sacrificial animal offered on Eid al-Adha), including:

- Ruling: The Hady is obligatory in Hajj due to a specific reason (such as Tamattu' or Qiran), whereas the Udhiyah is a confirmed Sunnah according to the majority of jurists. - Replacement of a Defective Animal: Malik permits replacing a defective Udhiyah with a better one, but he does not permit this for the Hady. - Place: The Hady is specific to Hajj and matters related to it, whereas the Udhiyah is not. - Place of Slaughter: The slaughter of the Hady is restricted to the Haram, while the slaughter of the Udhiyah is not restricted to a specific place.
