Abstract This article critically re-examines the legal and social framework governing religious freedom in Nigeria through the lens of the 2022 lynching of Deborah Yakubu, a student at Shehu Shagari College of Education. By positioning Yakubu’s death not merely as an isolated act of mob violence but as a metaphor for the systemic fragility of constitutional protections, the study explores the intensifying friction between secular law and religious sensitivities. The analysis focuses on three primary dimensions: The Conflict of Jurisdictions: The tension between the Nigerian Constitution’s guarantee of fundamental rights and the practical application of Sharia-influenced penal codes in Northern Nigeria. The Blasphemy Paradox: How the lack of a clear, uniform legal definition for "blasphemy" creates a vacuum where extrajudicial violence is often rationalized by communal religious norms. The State’s Failure to Protect: An assessment of the judicial and executive responses to the incident, highlighting a pattern of "soft" enforcement that inadvertently emboldens future vigilante actions. Ultimately, the article argues that safeguarding religious freedom in Nigeria requires more than legislative reform; it demands a fundamental re-negotiation of the boundaries between individual expression and communal piety. The study concludes that unless the Nigerian state asserts its role as the primary arbiter of justice over religious mobs, the "metaphor of Deborah Yakubu" will continue to represent a darkening horizon for human rights and national stability.
