Eid al-Adha (Festival of Sacrifice) is the latter of the two Eid festivals and is celebrated to commemorate the willingness of Prophet Ibrahim (as) to sacrifice his son, Prophet Ismail (as) as an act of obedience to Allah swt.
Men, women, and children are expected to dress in their finest clothing to perform Eid prayer in a large congregation in a mosque. Muslims who can afford to do so sacrifice their best domestic animals (usually sheep, but also camels, cows and goats) as a symbol of Ibrahim's sacrifice. The sacrificed animals, have to meet certain age and quality standards or else the animal is considered an unacceptable sacrifice. Generally, these must be at least a year old.
The regular charitable practices of the Muslim community are demonstrated during Eid al-Adha by the concerted effort to see that no impoverished person is left without sacrificial food during these days. Distributing meat among people is considered an essential part of the festival during this period, as well as chanting Takbir out.
Note :
I would like to wish my brother who (again!!!) is unable to celebrate Eid with the family in Kuala Lumpur - "Selamat Hari Raya Aidil Adha". Take care & may you be in the protection of Allah swt always.....
