In the past, Muslim scholars were elevated to leadership positions after receiving ijazas from deeply learned and upright Muslim teachers.

Now, scholars are elevated to leadership positions after receiving certificates of appreciation from the American Jewish Committee and other Zionist organizations.  

What kind of Musliks are stilling looking up to such scholars (e.g., Bin Bayyah, Hamza Yusuf, Rabbi Faris, etc.)?

Bin Bayyah and Hamza Yusuf are instrumental in fatwaCouncil.org that is collaborating with US to establish the IHRA definition of antisemitism. It’s already started in the USA and aims to suppress any support for Palestine.
