Id-ul-Azha, also known as Bakri Eid or Eid al-Adha, is a significant Islamic holiday commemorating Prophet Ibrahim's willingness to sacrifice his son Ismail as an act of obedience to Allah. It is celebrated on the 10th day of the Islamic month of Dhu al-Hijjah, involving the sacrifice of an animal (usually a goat or sheep). The holiday encourages Muslims to reflect on their own sacrifices for faith and strengthen their bond with Allah.
