Abraham serves as a shared meeting-ground figure for Muslims and Christians

Evidence

Perhaps the most interesting development has been the Maronite Fr. Y. Moubarac’s deeply original work, Abraham dans le Coran; its treatment of the Qur’an is revolutionary, in that it recognises, respects and uses critically the religious intention of the text; it also seeks in the figure of the Patriarch a common meeting-ground for Muslims and Christians. — Norman Daniel, Islam and the West, 1740
