His Noble Characteristics
We also find many accounts in relation to Hazrat Muhammad (sa) bin Maslamah being extremely judicious and acquiescent. Due to this, the Khulafa [Successors of the Holy Prophet (sa)] trusted him greatly. Hazrat Umar (ra) and Hazrat Uthman (ra) in particular had entrusted him with very important tasks and campaigns. When complaints were received against those who were appointed for various tasks in the administrative affairs, when complaints were received against them from other countries and places, Hazrat Umar (ra) would send Muhammad bin Maslamah to investigate these complaints.
