1.  Its definition: The sacrifices are the sheep, camels and cows that are slaughtered on the day of Al- Adha Eid and the days of Al-Tashreeq, approaching Allah, the Exalted.

2.  Its legality: The sacrifice is an obligatory tradition on the family of every Muslim house whose people are able to do it.  And that is due to the saying of Allah the Exalted: “ Therefore to thy Lord turn in Prayer and sacrifice” (108:2). 

And the saying of the Prophet sallallaahu álayhi wa sallam: “That who was to slaughter before the prayer let him repeat”. And the saying of Abu Ayyoob Al-Ansaari: “The man used to sacrifice one sheep on his behalf and on behalf of the family of his house, during the days of the Messenger of Allah”.(According to many scholars the sacrifice is optional ).  

3.   Its excellence: It is witness that the tradition of the sacrifice is of  great excellence, because of  the saying of the Messenger of Allahsallallaahu álayhi wa sallam:  “The son of Adam had never done a deed on the Day of Immolation more beloved to Allah than shedding the blood( of a sacrifice).  Sacrifice will come on the Day of Judgement with its horns , nails and  hair .Its  blood will fall in a place by Allah (The Exalted and Mighty) before it falls on the ground, so make the soul agreeable with it”.  And his saying sallallaahu álayhi wa sallam-when they had said to him: “what are the sacrifices?”- “It is the tradition of your father Ibraaheem.”  They said: “Then the wool?” He said: “In every hair of the wool there is a virtue.”
