To determine the legal status of an act of worship, identify its evidence, examine whether it is definitive or non-definitive, and then determine the consequence of performance and omission. Without this order, expressions such as “emphasized,” “binding,” and “rewarded” may be confused.
Example 1: The five daily prayers have a definitively established obligation.
Example 2: In the Hanafi scheme, witr is wajib: binding without sharing the definitive rank of fard.
Example 3: An emphasized Sunnah calls for maintained observance; unjustified disregard is not judged like omission of pure nafl.
Example 4: Extra voluntary prayer is rewarded but omission is not treated as neglect of fard.
The next distinct topic, ʿazimah and rukhsah, examines ordinary legal demands and legally recognized concessions.
