"One significance of Eid-ul-Adha is that it is a time of sacrifice.
Muslims commemorate phrophet Ibraham’s willingness to sacrifice everything for Allah including his beloved son, Ismael. Since Allah replaced Ismael with a lamb to sacrifice in place of his son, Muslims also offer the sacrifice of animals. The sacrifice can be done after the prayer on the 10th until 12th day of the al-Hijjah month before sunset. The meat of the animals is distributed among the relatives, the needy people and some portion is also kept for one one’s own consumption."
