What is the ruling on continuing to work at a religious institute that dictates that Ahl al-Sunnah wal-Jama'ah are the Ash'aris and Maturidis, given the inability to change this matter?

It is permissible to work in the institute if the majority of what is taught therein is sound, and slight errors in some subjects do not prevent this. Rather, it is prescribed to offer advice and clarification as much as possible. The Ash'aris and Maturidis are the closest among the theological sects to the Sunnah, and they are considered among Ahl al-Sunnah wal-Jama'ah (the People of the Sunnah and the Community) compared to the Mu'tazilah and the Rafidah.
