Ghawrath ibn al-Harith also known as Du'thar ibn al-Harith[1] [2] was a companion (Sahaba) of Muhammad. He was the first person to try and assassinate Muhammad during the Invasion of Dhi Amr.

While the enemy was watching, Ghawrath ibn al-Harith went to attack Muhammad. He threatened Muhammad with his sword and said "who will protect you from me on this day".

Muhammad then picked up the sword and said "who will protect you from me" then he forgave him.
