I was about to say forced conversion but Christians invented that shit on the 4th century...
I was also going to mention some of the maritime navigation tools used by the Portuguese and Spanish, yet, although the Muslims updated them they didn't create them, they just stole them from Levant pagans and Christians.
I dunno really...they created the Qur'an? Oh wait...most of Al-Qur'an's content comes from the Bible or from pre-muslim communities.
Fuck I give up!
