‘Eid Al-Adha is coming up. If you do this act on ‘Eid Al-Adha or the few days after, you will receive a great reward.
This is something that has been done since the beginning of time. It is also one of the most rewarding and respected rituals in Islam.
The concept of offering something to Allah goes back to Adam (AS). Qabil and Habil both offered a sacrifice to Allah. One was accepted and the other wasn’t. Qabil became jealous and angry and killed his brother.
However, the concept of a sacrifice goes back to Adam and his children. And then Prophet Ibrahim (AS) reintroduced the concept of the animal sacrifice instead of his son.
Since then Muslims have sacrificed an animal for Allah during this period of ‘Eid Al-Adha. Allah does not care about the flesh of the animal. It doesn’t reach Him.
What reaches Allah is the care that you show in this ritual. The way you cared for the animal, sacrificed it and then distributed the meat to the poor, this is what matters to Allah. This is what we will be rewarded for.
