Qurbani (Udhiyah) is the sacrifice of an animal performed during the days of Eid al-Adha, following the practice of Prophet Ibrahim (A.S.).
The days of Qurbani are the tenth, eleventh and twelfth of Zul Hijjah. The first day is better than the second, and the second better than the last.
It is more virtuous to slaughter the animal with one’s own hands. If one does not know how to slaughter, it is preferred that he remain present while someone else is sacrificing the animal. It is not necessary to make the niyyah (intention) of Qurbani with the tongue, however it is necessary to say Bismillahi Allahu Akbar when slaughtering.
If one has been favored by Allah with wealth, then he should also perform Qurbani on behalf of Rasoolullah (sallallahu alayhi wasallam), his Sahabah, his Ummah, the Prophets and for his own living or deceased relatives, friends and teachers who have conveyed Deeni knowledge.
One should always remember and never overlook our beloved Prophet (sallallahu alayhi wasallam) and perform Qurbani on his behalf. Aboo Talhah ( radhiyallahu anhu) has related that the Prophet (sallallahu alayhi wasallam) sacrificed one ram and while sacrificing the other he said, “This is on behalf of every one of my Ummah who believed in me and testified (to my prophethood).” (Tabrani)
It is a matter for deep thought and consideration that the Prophet (sallallahu alayhi wasallam ) kept his Ummah in his mind while offering the sacrifice and it is deplorable for the Ummah not to remember him at the time of Qurbani.
