The word mutawātir is connected with succession or repeated arrival. In technical usage it concerns a report established through a multiplicity of transmissions satisfying conditions that eliminate realistic concerted fabrication.
Suppose twenty people forward one person's message. There may still be only one original source. By contrast, people in separate towns describing a common occurrence on the basis of their own experience represent a different pattern of evidence.
These are teaching illustrations, not declarations that either specific example automatically meets the full technical standard. “Repeated frequently” and “supported by independent transmission” must not be treated as interchangeable.
