Furu al-din and practical duties
Religious practice includes prayer, fasting, pilgrimage, zakat, khums, and other normative duties.
What it is: Furu al-din are the practical duties and branches of religion. Depending on the Shi'i tradition, they include prayer, fasting, pilgrimage, zakat, khums, and other ethical and communal commitments.
How the religion understands it: Practice is not separated from doctrine. Ritual duties, economic solidarity, communal loyalty, and moral responsibility form an integrated whole.
Textual basis and context: The Qur'an, hadiths, and the jurisprudence developed by Shi'i jurists define these duties. In many Twelver contexts, khums and loyalty to the Ahl al-Bayt receive more visible emphasis than in usual Sunni summaries.
Debates and variations: There are internal differences over legal application, the authority of the jurist, religious financing, and the exact formulation of obligations.
