 In the late 6th century, the Al al-Ghawth and Al Jadila fought against each other in the 25-year-long Fasad War ("harb al-Fasad") in northern Arabia.Numerous atrocities were committed by both factions and the war resulted in the migration of several Jadila clans from the north Arabian plains to Syria, while the Al Al-Ghawth remained in Jabal Aja and Jabal Salma.The Jadila tribesmen founded a "hadir" (military encampment) near Qinnasrin (Chalcis) called "Hadir Tayyi" after the tribe.
