The difference between the Udh-hiyah and Hady

Question:
I will not go for Hajj this year and I want to offer a sacrificial animal and the process will be supported via a charitable organization. There are two options: Udh-hiyah and Hady. What is the difference between the two?
Answer:
All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
The Udh-hiyah differs from Hady, because Hady is a sacrificial animal that is offered to the sacred precincts, and the Udh-hiyah is a sacrificial animal that is slaughtered during the Days of Nahr with the intention of sacrificing. Offering an Udh-hiyah is an act of Sunnah for Muslims who can afford it, whether living in cities, towns, traveling or not, and for pilgrims in Mina and others, those who have Hady and those who do not have, as Ash-Shaafi‘i 
said.
According to Al-Mawsoo‘ah Al-Fiqhiyyah, the Udh-hiyah is defined as a sacrificial animal that is slaughtered during the Days of Nahr with the intention of seeking closeness to Allaah on specific conditions. Any animal that is slaughtered for other than that intention, such as those slaughtered for selling their meat, for food or for entertaining guests, is not a sacrifice. Also, animals that are slaughtered outside these days, even for drawing oneself closer to Allaah, are not considered Udh-hiyah as well. Other examples include the animals that are slaughtered with the intention of making ‘Aqeeqah, clearing liability as regards Tamattu' or Qiraan in Hajj, overlooking an obligation, committing a violation during Hajj, or as a Hady (the Hady is what is offered to the sacred precincts, including camels, cows, sheep, goats). All these are not Udh-hiyah.
It is now clear that the Hady is offered to sacred precincts only, contrary to the Udh-hiyah that is slaughtered anywhere. If the Udh-hiyah is slaughtered in the sacred precincts, it will be distinguished from Hady by virtue of the intention.
Allaah Knows best.
