Data collected through document analysis of the 17th Decree, Islamic texts, scholarly articles, and reports on social and religious ceremonies. Purposive sampling ensured sources were relevant, credible, and aligned with Islamic jurisprudence. Data analyzed through thematic analysis to identify, organize, and interpret key themes related to unlawful customs, their prohibition, social and economic impacts, and Islamically acceptable alternatives.

The 17th Decree promotes simple Nikah, community support, and Islamic principles to ensure harmony and well-being.
