Hazrat Zarrar and Hazrat Khaula (RA)
During the Battle of Bait Lihya, the Muslim Commander Zarrar(ra) was captured by the Byzantine forces. Word was sent to Khalid Bin Walid (ra) for further help.
Leaving the command of Damacus to Abu Ubaida (ra), Khalid( ra) set off to Bait Lihya with his mobile contingent of 4000 horsemen. As Khalid(ra ) approached the battle-field, he saw a muslim rider with a masked face gallop of towards the Byzantine front. This warrior would kill a number of the enemy soldiers, and then withdraw. He would after some time pounce on the enemy again and kill everyone who came his way. He was striking fear in the ranks of the enemy soldiers.
