Muslims around the world make animal sacrifice on Eid-ul-Azha to commemorate the sacrifice offered by Prophet Ibrahim (Abrahim).
According to belief, the Allah ordered Ibrahim to sacrifice his son Ismail. When the blindfolded father moved the blade on his son's throat to carry out the divine command, the Allah replaced Ismail with a goat, sparing Ibrahim the sorrow.
It is to celebrate the absolute submission of Prophet Ibrahim to the Allah and the saving of Ismail's life that Muslims offer animal sacrifice on Eid-ul-Azha.
It coincides with the Haj pilgrimage in Mecca and the sacrificial meat is distributed after the Eid prayers among the family, friends and the needy and the poor.
