What the Evidence Shows
The claim that atheism or apostasy is punishable by death in at least 14 Muslim-majority countries is largely accurate but slightly overstated in number. Multiple reputable sources from recent years consistently identify 13 countries where such penalties exist: Afghanistan, Iran, Malaysia, Maldives, Mauritania, Nigeria, Pakistan, Qatar, Saudi Arabia, Somalia, Sudan, United Arab Emirates, and Yemen.
These countries are all Muslim-majority and have legal frameworks or interpretations of Sharia law that allow for the death penalty for apostasy or atheism. The list in the claim matches these countries exactly but counts 14 instead of 13. No widely recognized source currently supports a total of 14 countries; the figure of 13 is standard in human rights and secular advocacy reports.
Additionally, some reports note that the enforcement and application of these laws vary significantly by country and over time. Therefore, while the list of countries is correct, the number should be 13 rather than 14 to align with authoritative sources.
