Overall judgment: The majority gives Sahih al-Bukhari general precedence in authenticity, followed by Sahih Muslim. Both enjoy exceptional scholarly reception, subject to specialized investigation of disputed individual reports.
Continuity criterion: the condition associated with Bukhari gives particular weight to demonstrable meeting; Muslim’s approach assigns more weight to possible contemporaneous contact in the appropriate context. Tadlis and proven obstacles to hearing require separate consideration under either approach.
Ranks of sound reports: source, compliance with both compilers’ conditions, compliance with one condition, and independent authenticity establish a general ordering, not an exceptionless rule. Strong independent routes, inferentially weighty contextual indications, and superior preservation can govern a particular comparison. The next topic is hasan li-dhatihi, where modestly reduced precision is distinguished from complete precision.
