 Already over 200 years ago the Noda Bihudah, in his sefer "Derushei HaTzlach", argued that the Zohar is to be considered unreliable as it came into our hands many hundreds of years after Rashbi's death and it lacks an unbroken "mesorah" as to its authenticity, among other reasons.Rabbi Qafiḥ identified a strong superstitious influence in Yemen which he saw as contrary to Orthodox Judaism.For example, his grandson Rabbi Yosef Qafih related one of many Yemenite customs for "חינוך הבית" whereby they would bake plain bread without salt and prepare "the table of appeasement."
