Are all the contents of the ḥadīth literature are the words of the Holy Prophet (sws)? Please give sufficient evidence if they are. If they are not, then why do we consider them ḥadīth?
Most of the ḥadīth narratives are transmission by meaning. It means that the narrator reports the message in his own words. We call such narratives ḥadīth because the narrator believes the narration to be a prophetic saying. It should also be noted that when a discipline is established and becomes mature the main words and expressions are used as term. In such a discourse, literal meanings go into background and lose central importance.
