«ثم المتواتر يوجب العلم القطعي ويكون رده كفراً»
The text assigns definitive knowledge to mutawatir transmission and describes denial of such established truth in grave terms.
This statement concerns denial of what is decisively established by genuine tawatur. A scholarly dispute about whether a particular report qualifies as mutawatir should not automatically be treated as denial of a decisively established religious truth.
The distinguishing feature is certainty of attribution, rather than practical confidence alone. This places mutawatir above mashhur and ahad in the presented hierarchy.
