On another occasion a person complained that Abu Musa Ash'ari had given him a lesser share than what he was entitled to. When the man saw Abu Musa he behaved rudely. Abu Musa felt annoyed, and had him struck with twenty lashes. He also had his hair shaved. The man complained to Umar, and Umar asked him to lay his complaint before a congregation in the mosque at Basra.. When the man laid his complaint before the congregation in the main mosque at Basra, Abu Musa admitted his mistake and said to the man "You can have your revenge. You may strike me with twenty lashes and have my hair shaved." The man felt satisfied and withdrew his complaint.
