What is Qurbani?
Qurbani, or Udhiyah as it known in Arabic, is the word that describes the sacrifice of an animal to Allah (swt) during the period of Eid ul Adha. 
On Eid Ul Adha, which marks the completion of the annual Hajj pilgrimage, the Muslim world celebrates and honours the tradition of the Prophet Ibrahim (PBUH) by sacrificing an animal and distributing the meat to those in need.

Who should perform Qurbani?
Udhiya demands that certain criteria must be met in order to be eligible for Qurbani. Any sane, adult, Muslim male or female who possesses the Nisab amount for Zakat must also perform the duty of Udhiya. Furthermore, Qurbani is also compulsory for every family member. In short, if you are eligible to pay Zakat, you must also perform Qurbani for yourself and every family member including children.

How many Qurbani animals do I have to sacrifice?
Qurban animals have shares. Sheep and goats have one share each, camels and cattle each have seven shares. So for a single person, Qurbani is fulfilled with a sheep or a goat. Up to seven people can share in the purchase of a cow or a camel, and the sacrifice will be made for the seven.
1 small animal (Sheep or Goat) = 1 Qurbani
1 large animal (Cattle) = 7 Qurbanis
You can make as many Qurbanis as you want – for example two or three shares in a cow or several sheep or goats – and on behalf of as many individuals as you like, including those who have passed away.

What animals are sacrificed at Qurbani?
The health and condition of the animal is also very important. Animals that are weak, blind, physically disabled, or those who are young, have broken horns or no teeth are ineligible. Regarding the types of animals that can be used for Qurbani, people generally opt for a goat. However sheep, cow, bull, buffalo or camel are also acceptable.

Do I have to record the name of someone else if I am giving Qurbani on their behalf?
Many people do record names. However, it is not necessary to give the name of the person, even if you are making a Qurbani on their behalf, as long as you have made the intention that you are giving the Qurbani on their behalf.

When is Qurbani performed?
Qurbani can be performed from the 10th day of the month of Dhul-Hijjah until the sun sets on the 12th of Dhul-Hijjah. The best time is to perform the act of Qurbani is immediately after the completion of the Eid-ul-Adha prayers.

How is Qurbani meat distributed?
Ideally, the meat from Qurban should be divided in three equal parts – one for the home, one for relatives and friends, and one for the poor and needy. The meat from Qurban can be distributed to the poor or rich, Muslim or non-Muslim. 
However, because of the relative lack of poverty in Western countries, many Muslims prefer to have their Qurbani performed in poorer countries or those in dire need, and the meat to be distributed to the neediest or those suffering adversity and poverty.
