Qatar operates under a legal and social framework rooted in Islamic law (Sharia) alongside civil statutes, enforcing several strict rules that visitors and residents must follow. Major restrictions include a zero-tolerance policy toward public intoxication, driving under the influence, and drug offenses, which carry severe prison sentences or deportation. Public displays of affection are strictly prohibited, and individuals are expected to dress modestly in public spaces, covering shoulders and knees. Additionally, photographing government buildings, military installations, and local residents without explicit permission is illegal, and importing pork products, electronic cigarettes, or certain non-Islamic religious texts or adult materials is heavily restricted or banned.
