The Islamic world was superior in technology in the age of the Crusades up until the Mamluks taking over Egypt. One of their leaders (I don’t recall the name) ordered the destruction of the rebuilt Library of Alexandria, saying that since the Koran was the word of God, and since all other books were either to reinforce that, or blasphemous, no other books were needed.
It was at that point Arab society lost its technological advantages and began to leech off the technological capabilities of the infidels, until this day.
