,السلام عليكم ورحمة الله وبركاته Is it permissible to teach at my local Masjid's (no 'Aqeedah is specified, but the temporary Imam is 'Ashari in 'Aqeedah) Sunday School, if I have made sure that the curriculum teaches the Salafi 'Aqeedah (An-Nasihah Islamic Curriculum)? !بارك الله فيك وأكرمك أستاذ

I do not know the names you have mentioned, but if you will teach people beneficial knowledge and you are qualified enough, then do so may Allah reward you there is a need for this.
