On the day after Hazrat ‘Uthmaan (radhiyallahu ‘anhu) accepted Islam, Hazrat Abu Bakr (radhiyallahu ‘anhu) brought the following luminaries to Rasulullah (sallallahu ‘alaihi wasallam):

Hazrat ‘Uthmaan bin Maz‘oon (radhiyallahu ‘anhu), Hazrat Abu ‘Ubaidah bin Jarraah (radhiyallahu ‘anhu), Hazrat Abu Salamah bin ‘Abdil Asad (radhiyallahu ‘anhu) and Hazrat Arqam bin Arqam (radhiyallahu ‘anhu).

All of them embraced Islam together in one sitting.
