The one great debt we owe to the muslims was back when they were into learning (before they decided that the only thing true was the Quran and therefore everything else is false) they preserved a good portion of the writings of Aristotle and also muslim scholars like Averroes wrote many treatises on them, and these became a huge part of the western scholarship and philosophy of the middle ages and down to today. You cannot mention the contributions of men like Thomas Aquinas or Albertus Magnus without also invoking Aristotle.

That idea was present from the beginning. They only preserved that which furthered some individual’s or some Caliph’s aims - all the rest they destroyed. When you read that so and so’s work has been lost - read destroyed by muslims in their “religious” fever.
We owe muslims nothing - they invented chattel slavery, destroyed everything not in the koran and murdered everyone that would not submit [several hundred millions to date].
