Collector of Charity & Spoils, and Supervisor of Security
The Holy Prophet (sa) sent Hazrat Abbad bin Bishr to Banu Sulaim and Muzaina in order to collect charity. Hazrat Abbad bin Bishr stayed with them for ten days. On the way back, he went to Banu Mustaliq in order to collect charity from them. He also stayed there for ten days. Following this, he returned to Medina. Similarly, it is also found in the narrations that the Holy Prophet (sa) appointed Hazrat Abbad bin Bishr as the collector of the spoils of the battle of Hunain. The Holy Prophet (sa) appointed him as the supervisor of security around the Holy Prophet (sa) during the battle of Tabuk.
