Sayyidah Ayshah (RA) narrated that Allahs Messenger said, “Of the deeds a man does on the day of sacrifice the dearest to Allah is the flow of blood (sacrifice). It will come on the day of Resurrection with its horns and its hair and its hoofs. Indeed, blood will be accepted by Allah at once even before it falls on the ground. So, please yourselves with it!
[Ibn e Majah 3126]
