If the Bahraini jihadi ideologue Turki al-Bin`ali personifies “the caliphate’s scholar-in-arms” for the Islamic State, one would find difficult to name a similar leading figure in al-Qa`ida’s ranks. Indeed, although most of the senior jihadi scholars sided with Ayman al-Zawahiri in his conflict with Abu Bakr al-Baghdadi, none of them actually belong to the organization. While the senior scholars certainly have longstanding ties to both al-Qa`ida’s leaders and rank and file and have been instrumental in furthering its agenda and that of its affiliates, they all remain independent from al-Zawahiri’s command.
With that said, al-Qa`ida has long strived to promote religious scholars in its ranks, such as Abu Yahya al-Libi and `Atiyyatullah al-Libi, who proved to be major influences in the militant landscape and in jihadi sympathizers’ circles. However, a sustained U.S. drone strikes campaign in Pakistan’s tribal areas removed these well-known heavyweights.
Over the remaining ideologues, the Palestinian Abu al-Walid al-Ghazi al-Ansari, also known as Abu al-Walid al-Filistini, represents the closest thing to a formal al-Qa`ida scholar today.
