Is it compulsory for the husband to make Qur'baani for his wife?

Answer

It is not the obligation of a man to make Qur'baani for his wife and adult children. If a husband makes Qur'baani for his wife who is alive, he requires her consent for the validity of the Qur'baani. If the adult children do not have the Zakaat Nisaab amount, then Qur'baani is not Waajib on them.
