You could make a good case that the history of social life is about the history of the technology of memory. That social order and control, structure of governance, social cohesion in states or organizations larger than face-to- face society depends on the nature of the technology of memory--both how it works and what it remembers... In short, what societies value is what they memorize, and how they memorize it, and who has access to its memorized form determines the structure of power that the society represents and acts from.
The people of the Qur’an (those who recite and those who memorize the Qur’an) will be in the highest level (in Heaven) from amongst all of the people with the exception of the Prophets and Messengers. Thus, do not seek to degrade the people of the Qur’an, nor take away their rights, for surely they have been given a high rank by Allah.
Write knowledge since you can’t memorize unless with writing. Heart confides to the written.
