Mistake 1: Every marfūʿ report is musnad. Correction: This definition additionally requires a Companion's attribution and apparent continuity.
Mistake 2: Every musnad report is sound. Correction: Apparent continuity does not prove every authenticity condition.
Mistake 3: The shortest chain always wins. Correction: A more reliable longer route may be preferred.
Mistake 4: Badal and muwāfaqah are the same. Correction: The former converges at the teacher's teacher, the latter at the compiler's teacher.
Mistake 5: Musāwāh and muṣāfaḥah require an actual meeting. Correction: Their central feature is numerical equivalence.
Conclusion: Interpret each hadith term by its precise definition, its endpoint, the convergence of routes, their counts, and the reliability of narrators.
