If your new to Indonesia and are wondering why there are simply loads of goats, cows and buffalo tied up everywhere with families and children staring and pulling at them, it is because tomorrow is the Islamic festival to commemorate the willingness of Ibraham or Abraham to follow Allah's command to sacrifice his son Ishmael and they will be slaughtered as part of their belief.
People buy a goat, cow or buffalo and then have it slaughtered for the sacrifice and the meat is given to the local poor people. It is also when the main pilgrimage to Mecca often begins.
It's a tradition here and always has been. However if you are not into watching animals being killed and skinned as you wander around the city then best stay in tomorrow. It's not everyone's cup of tea but it is a very important day for Muslims. However most of the animals are butchered near mosque's and behind fences but should you turn up with a camera I am sure the butchers will smile for you.
A goat costs from just over a 1 million and the sky is the limit for cows and buffalo's depending what kind you want to donate.
