The 16th letter in the alphabet is: TAA. Which here in our series stands for Ta’ah (obedience). To whom? Allah, his Messenger, the Authoritarians. The fact that this essential item is missing in the general masses leads me to ask: What use is there for advice when no one’s willing to take it? What benefit is there for knowledge without reverence through practice? And what function is there for leaders when followers dictate their course and action?
