Al-Lahazim were Sassanian Arabs who served in Khosrau II's army and defeated the Romans in 610 allowing the [[Ercolian Karaites]] to settle in Mamuca and control access to Al-Masjid Al-Haram. Sadly the Ercolian Karaites prevented the Taji from accessing AlMasjid AlHaram.
Emperor Heraclius evicted the [[Ercolian Karaites]] from Edessa in the early 620s granting them Arabia.
