Could you provide reference for this?
Ibn Shihab Az Zuhri (rahimahullah) said regarding Ummul Mu’minin Sayyidah ‘Aaishah (radiyallahu ‘anha):
“If the knowledge of ‘Aaishah (radiyallahu ‘anha) was collected and [compared to] the knowledge of all people as well as the knowledge of the other wives of Nabi (sallallahu ‘alayhi wa sallam), the knowledge of ‘Aaishah (radiyallahu ‘anha) would be greater”
Imam Hakim (rahimahullah) has recorded this narration in his Mustadrak.
