Introduction
Then, there is a companion by the name of Hazrat Abbad bin Bishr, who passed away during the battle of Yamama in the eleventh year after Hijra. Hazrat Abbad bin Bishr’s title was Abu Bishr and Abu Rabi. He belonged to the tribe of Banu Abd-ul-Ash‘al. He only had one daughter, who also passed away. In Medina, he accepted Islam at the hand of Hazrat Mus‘ab bin Umair, prior to Hazrat Sa‘d bin Mu‘adh and Hazrat Usaid bin Uzair. At the time of forming bonds of brotherhood in Medina, the Holy Prophet (sa) formed a bond of brotherhood between him and Hazrat Abu Hudhaifa bin Utba. Hazrat Abbad bin Bishr participated in the battles of Badr, Uhud, Khandaq and all other battles alongside the Holy Prophet (sa). He was among those companions, who were sent by the Holy Prophet (sa) in order to execute Ka‘b bin Ashraf.
