This is not a new phenomenon on the Persian Gulf: religious sheikhs (clerics) for hire.
Often they come from Egypt, Jordan, North Africa and other Arab countries/regions. They usually attach themselves to one or another among the ruling absolute oligarchies, of the Gulf, especially in the UAE or Qatar. Attracted by money and opportunity, they start issuing statements or Fatwas in favor of their benefactors and against others who displease these benefactors. They are absolutely mercenaries: clerics for hire. No different from the armed foreign mercenaries that some Gulf regimes hire to do their repression or wage their regional wars.
Here is a man with the impressive-sounding title of Deputy President of the International Union of Muslim Clerics, basically a clerical bureaucracy for hire. He is here accusing another cleric-for-hire, the Religious Adviser, whatever that be, of the top man in the UAE, Mohammed Bin Zayed (MBZ), of being among “devil worshipers”. He also called him a religious traveling salesman. MBZ and the UAE are among the strongest anti-Muslim Brotherhood in the whole Middle East. This is a sore point of contention with their Saudi “allies” in the stalling war on Yemen.
Of course all this name-calling is a case of one soot-covered pot calling another pot ‘black’.
The Persian Gulf GCC states are full of these hired expatriate clerics, like Al Qaradawi (in Qatar) and others, basically mercenaries, religious guns for hire. Often they are either Muslim Brothers who have found the joys of oil money (in Qatar) or others hired by the UAE potentates to blast the Muslim Brotherhood. Islamic gunslingers and mud-slingers.
All these people do their own interpretation of the Quran or Hadith to serve their masters. They are almost as bad as the Salafis, almost.
