I remember hearing that it was a long-held tradition for people to hand transcribe their own copies of the Quran. I’ve not seen many, but those I have seen are beautiful.
And in Judaism, you need to memorize portions of the Torah to indicate you are ready for adulthood.
Interestingly, there’s no similar demand for close acquaintance with the Bible among Christians. Indeed, the appeal to the illiterate was so strong that story panels in churches were made to allow those who could not read to visually see the stories.
Just saying.
