The following is an excerpt taken from Islamic Months authored by Mufti Muhammad Taqi Usmani.
The Urdu and persian word Qurbani (Sacrificial slaughter) is derived from the Arabic word Qurban. Lexically, it means an act performed to seek Allah’s pleasure. Originally, the word Qurban included all acts of charity because the purpose of charity is nothing but to seek Allah’s pleasure. But, in precise religious terminology, the word was later confined to the sacrifice of an animal slaughtered for the sake of Allah.
