What is Qurbani/Udhiya?
Qurbani/Udhiya during Eid-ul Adha is an act to commemorate Prophet Ibrahim’s sacrifice as mentioned in the Quraan.
And, when he (his son) was old enough to walk with him, he said: “O my son! I have seen in a dream that I am slaughtering you (offer you in sacrifice to Allah), so look what you think!” He said: “O my father! Do that which you are commanded, Insha’ Allah (if Allah will), you shall find me of As-Sabirin (the patient ones, etc.).” Then, when they had both submitted themselves (to the Will of Allah), and he had laid him prostrate on his forehead. And We called out to him: “O Abraham! You have fulfilled the dream (vision)!” Verily! Thus do We reward the Muhsinun (good-doers).Verily, that indeed was a manifest trial. And We ransomed him with a great sacrifice (i.e. a ram). And We left for him (a goodly remembrance) among generations (to come) in later times. (Sura Saffat, verses 102-108.)
Prophet Muhammad (PBUH) taught Muslims the way of remembering the act of Ibrahim. He stayed 10 years in Madina and performed sacrifice at Eid-ul-Adha. (Tirmidhi)
Qurbani in Islamic terms means the slaughtering of an animal with the intention of getting close to Allah (SWT) by giving some or all of the meat to the poor and destitute. Animals that can be sacrificed are goats, cows and camels. They are sacrificed on the day of Eid-ul-Adha and also on the three days after (the 11, 12 and 13th of Dhulhijjah).
What are the Benefits of Qurbani?
Giving meat to the poor and destitute as required when doing Qurbani spreads happiness so they may also enjoy the event of Eid-ul-Adha as it is a time of celebration and festivities for all Muslims.
Who should give Qurbani?
Persons who possess Nisab (minimum amount of wealth requiring them to pay Zakat) should give Qurbani.
Although Qurbani is wajid in Islam for the person who posses Nisab, it should not be a matter of pride. Islam is against of the evil of pride.
