Billions of Muslims worldwide joined together to celebrate the religious holiday, Eid al-Adha, also known as the Feast of Sacrifice. This significant religious observance commemorates Prophet Ibrahim's act of obedience to God, as he was willing to sacrifice his son. Muslims mark the occasion with prayer, feasting, and acts of charity. On this day, people sacrifice an animal like a goat, sheep, or cow, and then share the meat with their neighbors, family members, and those in need. ECI reports, citing Anadolu Agency.
