Ghwarath ibn al Harith

Ghwarath ibn al-Harith also known as Du'thar ibn al-Harith was a companion (Sahaba) of Muhammad. He was the first person to try and assassinate Muhammad during the Invasion of Dhi Amr. According to Muslim scholar Sami Strauch, it is reported in Sahih Bukhari that it was raining, and Muhammad took his garments off and hung it on a tree to dry, while the enemy was watching, Ghwarath ibn al-Harith went to attack Muhammad. He threatened Muhammad with his sword and said "who will protect you from me on this day". Then according to Muslim Scholars the Angel Gabriel came and thumped Ghawrath in the chest and forced him to drop his sword. Muhammad then picked up the sword and said "who will protect you from me".
