Bond of Brotherhood
There is a tradition in Al-Tabaqaat-ul-Kubra stating that when Hazrat Utbah (ra) bin Ghazwan and his freed slave, Khabbab, migrated towards Medina, they stopped at Quba and stayed in the house of Hazrat Abdullah bin Salama Ajlani. When Hazrat Utbah (ra) arrived in Medina, they stayed at Abbad bin Bishr’s house. The Holy Prophet(sa) established a bond of brotherhood between Hazrat Utbah (ra) bin Ghazwan and Hazrat Abu Dujana (ra).
