Is one Qurbani sufficient on behalf of a family or is each eligible person required to do his/her own Qurbani?
As Salaamu Alaikum wa Rahmatullah wa Barakatuh
Many people have a misunderstanding that one animal is sufficient on behalf of a whole family. This is not the case. Rather, each individual who fulfills the required conditions of Qurbani must make Qurbani on his own behalf. A collective Qurbani will not be permissible.
