«وَفِي مُسْنَدِ الْبَزَّارِ وَالْمُعْجَمِ الْأَوْسَطِ لِلطَّبَرَانِيِّ أَمْثِلَةٌ كَثِيرَةٌ لِذَلِكَ»
Numerous examples of this kind occur in the Musnad of al-Bazzar and al-Tabarani's al-Muʿjam al-Awsat.
Musnad al-Bazzar is a hadith compilation associated with Abu Bakr al-Bazzar, while al-Muʿjam al-Awsat is a work of al-Tabarani. Both are important places to examine unusual or individual transmission routes.
Merely finding a narration in one of these collections does not amount to a ruling of authenticity. A collection can be a source for tracing singular routes, whereas acceptance still requires evaluating its chain, the text, and relevant hidden defects.
Thus “where was this report recorded?” and “how well supported is its transmission?” remain separate research questions.
