The First Muslim to Perform Hijrah with his Family:

Hazrat Anas (radhiyallahu ‘anhu) reports that Hazrat ‘Uthmaan (radhiyallahu ‘anhu) had left for Abyssinia, performing Hijrah with his respected wife, Hazrat Ruqayyah (radhiyallahu ‘anha), the blessed daughter of Rasulullah (sallallahu ‘alaihi wasallam). News of their condition was delayed, and hence Rasulullah (sallallahu ‘alaihi wasallam) became concerned and would come out of Makkah Mukarramah, seeking information in their regard. Eventually, a woman came to Rasulullah (sallallahu ‘alaihi wasallam) and gave him information regarding them. On this occasion, Rasulullah (sallallahu ‘alaihi wasallam) remarked, “Hazrat ‘Uthmaan (radhiyallahu ‘anhu) is the first person to perform Hijrah in the path of Allah Ta‘ala with his family after Nabi Lut (‘alaihis salaam).”
