 One of the failures of the school, according to Yemen's last Chief Rabbi, Rabbi Amram Qorah, was that by teaching the Turkish language, their study of Hebrew suffered, seeing that the Jewish youth had less time to fully acclimate themselves to the rules of Hebrew grammar and to the finesse of the language.During this time, the controversy over the study of the Zohar worsened.After being incarcerated twice by Muslim authorities in 1914, being released only in Adar of 1915, Rabbi Qafiḥ regretted his earlier reticence in not speaking out against certain ills of the community.
