In Islam, animal blood sacrifice, known as "Qurbani" or "Udhiyyah," is a ritual performed during the month of Dhul Hijjah, specifically on *Eid al-Adha. It commemorates Prophet Ibrahim's (Abraham) willingness to sacrifice his son Ismail (Ishmael) for God.

The origins of Islam are often traced back to the patriarch Abraham and his son Ishmael. This connection is significant in Islamic tradition and is reflected in various religious texts and teachings.
