Musnad is a collection of ahādīth arranged

Musnad is a collection of ahādīth arranged according to the names of their authorities. This means that the hadiths are organized based on the companions of the Prophet Muhammad (peace be upon him) who narrated them, and not based on specific topics or in alphabetical order. The word "Musnad" itself means "supported" or "founded upon," which reflects the importance placed on the chain of narrators in authenticating the hadiths.
