Qur'anic rulings extend beyond ritual worship to several areas of life. The classification names worship, transactions, household governance and civic or public affairs.
Worship: prayer, fasting and other devotional duties.
Transactions: rights, exchanges and obligations among people.
Household affairs: family relations and domestic responsibilities.
Public affairs: social order, common responsibilities and public welfare.
The categories reveal the range of the Qur'an's practical guidance, while detailed subsidiary rulings belong to the specialized methods of jurisprudence.
