«Kadhaba» and «yakdhibu» constitute severe criticism. In any particular instance, the evidence must establish whether deliberate fabrication, a false attribution to a teacher, or a demonstrable conflict is at issue.
Yūnus’s broad criticism is reported first; ʿAwf and Ayyūb then give specific cases. These help contextualize the criticism. They do not imply that every wording cited from ʿAmr is intrinsically false.
