Hijrah to Madinah Munawwarah:

Hazrat ‘Uthmaan (radhiyallahu ‘anhu) and his respected family, Hazrat Ruqayyah (radhiyallahu ‘anha), eventually returned to Makkah Mukarramah from Abyssinia. They thereafter performed Hijrah to Madinah Munawwarah. When Hazrat ‘Uthmaan (radhiyallahu ‘anhu) arrived in Madinah Munawwarah with his respected family, he was hosted by Hazrat Aws bin Thaabit (radhiyallahu ‘anhu), the brother of Hazrat Hassaan bin Thaabit (radhiyallahu ‘anhu).
