Sa'd ibn Ubadah
When the Treaty of Hudaybiya was being written, Suhayl ibn Amr referred to Muhammad as "Muhammad ibn Abdullah" because he did not believe he was God's Messenger. Sa'd ibn Ubadah and Usayd ibn Hudayr seized the clerk’s hand and warned him: "Write 'Muhammad, the Messenger of God' or the sword will be between us. We won't allow this insult to our religion!" Muhammad tried to calm them and gestured for quiet, before agreeing to write a contract between "Muhammad ibn Abdullah and Suhayl".
