Assessment

Shahid considers the existence of Jabala as possible "evidence" for the Byzantines' revival of the Ghassanid phylarchate following its destruction during the Sasanian Persian invasion of Byzantine Syria in 614. In the view of historian Julia Bray, Jabala's references in the Islamic liteature represents "the archetype" of the bygone era "of , Christianity, and kingship" in Arab history, and the transition to the new Islamic era. The historian Greg Fisher assesses Jabala as "a semi-mythical figure" used in the literature to "test the purity of the new uslimfaith, celebrate the greatness of the empire that the uslim conquerorssupplanted, and serve all kinds of other useful literary and rhetorical purposes".
