A sacrifice is definitely made with a sheep or a goat.
Consider the festival.
Then it turns out that the knife is first used on the throat.

Your Eid is over.
But the one who has been sacrificed.
He has been sacrificed.
How is his Eid?????????????
The philosophy of life is to sacrifice oneself for the happiness of a loved one.
A Khalil Allah became only when Ishmael (peace be upon him) was made to pass through the stage of Zabih Allah.

This is the philosophy of Abraham (peace be upon him) of shedding blood throughout the world.
The act of a beloved Khalil Allah was so loved that this Sunnah of sacrifice was established until the Day of Judgment.
The reason is simple.

Whoever becomes Allah's
Allah is therefore sufficient in every respect.
He is also the Healer.
And the glory of that Wali Allah would be exalted until the Day of Judgment. Running (Sa'i) between Safa and Marwah was also the act of a Wali Allah.
