Abstract This article aims at analyzing how the penetration of a commercial rational into the religious field impacts the relations between the State and the Muslim religion in the case of post-Soviet Russia. Here, the rise of a ‘halal market’ – that is the market for halal products and the market of halal certification – was punctuated by scandals. This research scrutinizes one of them, linked with halal meat products containing pork dna. This scandal is studied as it reveals the pre-existing order and is considered per se, as a critical test when common values and norms are either abandoned or strengthened, and previously established relations are transformed. First, the article presents how Islam is organized and regulated in the Russian Federation; then it analyzes the ‘scandalization strategy,’ which leads to the reconfiguration of the game of actors. Lastly, it examines how the scandal, through the use of law and court decisions, contributes to the extension, legitimization and consolidation of the certificated ‘halal’ norm beyond the circles of pious Muslims. This research is based on empirical data gathered in Moscow and Kazan in 2018: the observation of a court trial and the analysis of documents relating to the legal proceedings, semi-structured interviews and online research.
