When Hazrat Abu Bakr (radhiyallahu ‘anhu) proposed for Hazrat Faatimah (radhiyallahu ‘anha), then he did so via his daughter, Hazrat ‘Aa’ishah (radhiyallahu ‘anha). Likewise, when Hazrat ‘Umar (radhiyallahu ‘anhu) proposed for Hazrat Faatimah (radhiyallahu ‘anha), he sent the proposal via his daughter, Hazrat Hafsah (radhiyallahu ‘anha).

As for Hazrat ‘Ali (radhiyallahu ‘anhu), then when he intended to propose for Hazrat Faatimah (radhiyallahu ‘anha), he did not have a close female relative living in the home of Rasulullah (sallallahu ‘alaihi wasallam) via whom he could send his proposal. Hence, he personally came to Rasulullah (sallallahu ‘alaihi wasallam) to propose for Hazrat Faatimah (radhiyallahu ‘anha).
