Eid-ul-Adha is celebrated around the world on the last day of the Hajj pilgrimage. In my country the Maldives we simply call it Bodu Eid (big Eid).
In Bangladesh, where I am completing my medical internship, this Eid day is referred to as Qurbani (sacrifice). The festival commemorates Prophet Ibrahim’s (Abraham) willingness to follow God’s command to sacrifice his son Ishmael and Ismael’s consent to being sacrificed. Wen we were kids, we used to sacrifice chicken at the back of our house as was the custom in Maldives. Nowadays however we simply buy the meat from the store.
However in Bangladesh sacrificing of animals is taken very seriously even now. The last couple of days on my trek to the hospital I’ve seen Ox’s (oxen?) tied to posts on various places. Today after the Eid prayer the sacrifice was done on the streets itself. The drains on our street and the next were red with Ox blood
