A word Qurban means sacrifice. It is used for a variety of sacrifices offerings including animal sacrifice. This is the main reason of sacrificing animals that to accept Allah only and only one God. It is demonstration of total submission to Allah and a proof of complete obedience to Allah’s will, orders and commands.
Dear brothers and sisters, the sacrifice of animals “Udhiya” was so much important in the eyes of Prophet (PBUH) that he instructed Hazrat Ali to do it after Prophet’s (PBUH) death. Hazrat Hanash reported that I saw Hazrat Ali sacrificing two sheep. I asked him, “What is this and why are you sacrificing two animals?” Ali said: “Verily the Messenger of Allah (PBUH) left instruction to me to scarifice on his behalf, and so I am sacrificing on his behalf.
In another hadith Prophet (PBUH) said “Whoever has the capacity to sacrifice (animal) and does not do so, should not come to the place where the Eid prayer is offered.” (Ibn Majah). We can understand the importance of “Udhiya” from the above ‘Hadith’ therefore each and every Muslim who is obliged, who have prescribed wealth should offer it.
