This article is based on thirty years of observations of the sacrificial practices that are integral to the Muslim celebration of Eid al-Adha. Conducted in several urban settings in France, it describes the evolution of this ritual sacrifice and how it is practiced in different contexts. The study focused on a variety of specific sites ranging from densely populated suburban areas, foreign worker residences, municipal properties, and farms and slaughterhouses in the 1980s. Additional locations observed for the study include areas that were specifically set aside by officials in the 1990s, as well as the more recent confinement of the practice to established and temporary slanghterhouses since the early 2000s. The article also describes changes in methods for obtaining sacrificial sheep, including ordering them from Muslim butchers and purchasing them in large supermarkets or on the internet. More recently, Muslim authorities encourage replacing ritual sacrifice with donations to charitable organizations as an alternative way of celebrating Eid al-Adha in France, as well as in the Maghreb and West Africa.
