Answered by Shaykh Yusuf Weltch
When I first began practicing Islam, I followed the ruling that offering Qurbani is a Sunna, not a Wajib. However, after a few years, I began to follow the Hanafi madhab, but I had no idea that Qurbani was considered necessary.
So I’ve missed roughly ten years of Qurbani since I first began practicing (my wealth was always above the Nisab). Is it necessary for me to make-up missed Qurbani?
In the Name of Allah, the Most Merciful and Compassionate
In normal cases, it would be obligatory to make up the slaughter or to give the value of the slaughter animal to charity. [Ibn ‘Abidin, Radd al-Muhtar]
However, in your case, since you did not know of the obligation of slaughtering (Qurbani), you are not obliged to make-up for missed slaughters. This is because from the conditions for an act of worship to be obligatory on someone is that they have knowledge of its obligation or live in a place where such knowledge is easily accessible or widespread. [Ibid.]
You are not obliged to make-up for any missed Qurbani sacrifices up till now, however, moving forward, if you meet the requirements, such as the nisab, you must perform the Qurbani.
Hope this helps
Allah knows best
