Wahshi ibn Harb

Waḥshī ibn Ḥarb (Arabic: وحشي بن حرب, lit. 'The Savage, Son of War'), also known as Abu Dusmah was a former slave of Jubayr ibn Mut'im before becoming a freedman and a Sahabi (companion of the Islamic prophet Muhammad). He is best known for killing a leading Muslim fighter, Hamza ibn ‘Abd al-Muttalib, Muhammad's uncle, prior to converting to Islam, and afterwards reportedly killing Musaylimah, the leader of an enemy apostate army waging war against the Muslims.
