Qurbani is expected by every non-disabled Muslim who has reached the age of puberty and for everyone that meets the rules of Zakat.
There are different schools of thought on who Qurbani is Wajib for, and you should speak to your local Imam for confirmation. Qurbani provides families in need with necessary food for the celebration of Eid, and your donation, if you are able and eligible to make one, is gratefully received
