Sacrifice is the offering of material possessions or the lives of animals or humans to a deity as an act of propitiation or worship. Evidence of ritual animal sacrifice has been seen at least since ancient Hebrews and Greeks, and possibly existed before that.

Varieties of ritual non-human sacrifices are practiced by numerous religions today.Animal sacrifice
Animal sacrifice is the ritual killing of an animal as part of a religion. It is practiced by adherents of many religions as a means of appeasing a god or gods or changing the course of nature. It also served a social or economic function in those cultures where the edible portions of the animal were distributed among those attending the sacrifice for consumption. Animal sacrifice has turned up in almost all cultures, from the Hebrews to the Greeks and Romans (particularly the purifying ceremony Lustratio), Egyptians (for example in the cult of Apis) and from the Aztecs to the Yoruba.
The religion of the ancient Egyptians forbade the sacrifice of animals other than sheep, bulls, calves, male calves and geese.Animal sacrifice is still practiced today by the followers of Santería and other lineages of Orisa as a means of curing the sick and giving thanks to the Orisa (gods). However, in Santeria, such animal offerings constitute an extremely small portion of what are termed ebos—ritual activities that include offerings, prayer and deeds. Christians from some villages in Greece also sacrifice animals to Orthodox saints in a practice known as kourbánia. The practice, while publicly condemned, is often tolerated.Islam
An animal sacrifice in Arabic is called ḏabiḥa (ذَبِيْحَة) or Qurban (قُرْبَان) . The term may have roots from the Jewish term Korban; in some places like Bangladesh, India or Pakistan, qurbani is always used for Islamic animal sacrifice. In the Islamic context, an animal sacrifice referred to as ḏabiḥa (ذَبِيْحَة) meaning "sacrifice as a ritual" is offered only in Eid ul-Adha. The sacrificial animal may be a sheep, a goat, a camel, or a cow. The animal must be healthy and conscious.
..."Therefore to the Lord turn in Prayer and Sacrifice. " (Quran 108:2) 
Qurban is an Islamic prescription for the affluent to share their good fortune with the needy in the community.
On the occasion of Eid ul Adha (Festival of Sacrifice), affluent Muslims all over the world perform the Sunnah of Prophet Ibrahim (Abraham) by sacrificing a cow or sheep. The meat is then divided into three equal parts. One part is retained by the person who performs the sacrifice. The second is given to his relatives. The third part is distributed to the poor.
The Quran states that the sacrifice has nothing to do with the blood and gore (Quran 22:37: "It is not their meat nor their blood that reaches God. It is your piety that reaches Him..."). Rather, it is done to help the poor and in remembrance of Abraham's willingness to sacrifice his son Ismael at God's command.
The Urdu and Persian word "Qurbani" comes from the Arabic word 'Qurban'. It suggests that associate act performed to hunt distance to Almighty God and to hunt His sensible pleasure. Originally, the word 'Qurban' enclosed all acts of charity as a result of the aim of charity is nothing however to hunt Allah's pleasure. But, in precise non-secular nomenclature, the word was later confined to the sacrifice of associate animal slaughtered for the sake of Allah.A similar symbology, which is a reflection of Abraham and Ismael's dilemma, is the stoning of the Jamaraat which takes place during the pilgrimage.
