General criticism: Yūnus’s statement, «yakdhibu fī al-ḥadīth».
Specific attribution challenge: ʿAwf’s objection to the claimed route through al-Ḥasan for a known Prophetic text.
Conflict with direct testimony: Ayyūb’s direct hearing from al-Ḥasan of a contrary statement.
Triggers for further scrutiny: Unusual reports and the chronology of hearing.
These sources concern one transmitter but have different evidentiary scope. Sound analysis tracks the speaker, basis and limits of each criticism.
Al-Nawawī distinguishes two possible domains of the criticism directed at ʿAmr: where Prophetic hadith is being attributed, the concern is false attribution to the Messenger ﷺ; where opinions and doctrines are at issue, the warning may concern innovation or departure from the scholarly majority. The distinction does not turn every juristic disagreement into “lying”; each allegation must be evaluated within its particular evidentiary context.
