Determine the right and its effect before selecting the standard of proof.
A qualifying solitary report may establish a non-punitive divine matter. Establishing an enforceable private claim against another person invokes both number and integrity. In ordinary non-compulsory dealings, one speaker’s communication can guide practical action. In revocation of an existing authority, Imam Abu Hanifa’s intermediate category requires either number or integrity.
Mistaken inference: “One person is reporting; therefore one uniform legal rule applies everywhere.”
Sound inference: “The same form of information can have different evidentiary functions in different legal settings.”
This keeps the legal treatment of worship, market dealings and court disputes in their distinct categories.
