Family Ties with Rasulullah (sallallahu ‘alaihi wasallam):

Hazrat Jaabir bin ‘Abdillah (radhiyallahu ‘anhu) narrates that Hazrat Sa’d (radhiyallahu ‘anhu) once arrived when Rasulullah (sallallahu ‘alaihi wasallam) said, “This is my maternal uncle. Which person can show me a maternal uncle like mine.”

Note: Rasulullah (sallallahu ‘alaihi wasallam) referred to Hazrat Sa’d (radhiyallahu ‘anhu) as his maternal uncle (despite him not being the brother of Nabi (sallallahu ‘alaihi wasallam)’s respected mother) because Hazrat Sa’d (radhiyallahu ‘anhu) hailed from the Banu Zuhrah tribe and the respected mother of Rasulullah (sallallahu ‘alaihi wasallam), Hazrat Aaminah, also hailed from the Banu Zuhrah tribe.
