His Father
The father of Hazrat Bishr (ra), Hazrat Bara bin Ma‘rur (ra) was among the twelve appointed chiefs during the Second Bai‘at at Aqabah and was the chief of the tribe of Banu Salama. Hazrat Bara (ra) passed away during a journey one month prior to the migration to Medina. When the Holy Prophet (sa) had migrated to Medina, he visited his grave and recited four takbirat.
