Also there is dispute if there are any Mutawattir hadith at all ...In another article on this site ... pls see the below comments ....
QuoteThe vast majority of the Ahadith corpus is based on an 'ahad' transmission which merely provides nothing more than a single source of evidence. So in effect, what one originator narrates, no other narrator passes on the same hadith. It is argued whether any 'tawatur' hadith (multiple sources of hadith) actually exist, and if so, what they actually are. What one scholar may consider as 'tawatur' may be rejected by another, hence the subjectivity inherent in the enterprise.
