It was the habit of Shaikhul Hadith, Moulana Muhammad Zakariyya رحمه الله that during the days of Qurbani, he would not partake of any food except the meat of Qurbani to this extent that he would even leave out eating bread (roti). He would say that when Allah Ta’ala has blessed us with this meat, then how can we partake of any other food? This will amount to disrespecting the invitation of Allah Ta’ala.
We should also try our best to follow this great Sunnah of Nabi صلى الله عليه وسلم on the days of Eid. (Virtues of Qurbani pg.26)
