Animal sacrifice
Animal sacrifice is the ritual killing of an animal as practiced by many religions as a means of appeasing a god or spiritual being, changing the course of nature or divining the future. Animal sacrifice has occurred in almost all cultures, from the Hebrews to the Greeks and Romans to the Yoruba. Over time human and animal sacrifices have become less common in the world, such that modern sacrifices in the West are rare. The practice of animal sacrifice is still common in Islamic society however, particularly during the festival Eid al-Adha. Affluent Muslims who can afford it sacrifice their best halal domestic animals (usually a cow, but can also be a camel, goat, sheep or ram depending on the region) as a symbol of Abraham's willingness to sacrifice his only son. The sacrificed animals, called aḍḥiya (Arabic: أضحية), known also by the Perso-Arabic term "qurbāni", have to meet certain age and quality standards or else the animal is considered an unacceptable sacrifice. This tradition accounts for the slaughter of more than 100 million animals in only two days of Eid. In Pakistan alone nearly 10 million animals are slaughtered on Eid days costing over US$3 billion. Most religions condemn the practice of human sacrifices, and present day laws generally treat them as a criminal matter. Nonetheless traditional sacrifice rituals are still seen in rural areas where the state monitors less closely .
