Origins of the Spanish Language
It may surprise many people that Spanish has Muslim roots. Just as Turkish it used to be written in Arabic script until it got forcefully latinized.
Aljamiado
Aljamiado played an important role of preserving Islam and the Arabic language in Andalus (Islamic Spain). Aljamiado is a Arabic corruption of the word "Ajamiyah" which meant "foreign language" this term was used to mostly describe the Roman languages in Europe. After the fall of Andalus the Moriscos were forced to convert to Christianity or got kicked out of Andalus if they didn't.
Latinization
For the Moriscos that stayed in Spain they were subjected to harsh cruelty. They were forced to adopt Christian beliefs and traditions as well as be forced to go to church on Sunday's. In 1567 Philip II issued an order which forced all the Moriscos to abandon Arabic in every way whether it meant speaking or writing it otherwise it would be regarded as a crime. They were given 3 years to learn the Christian Latin version of Spanish, after that they would destroy there materials written in Arabic. Moriscos translated all prayers and the sayings of their prophet Mohammed into Aljamiado, but kept all the Quranic verses in the original Arabic. These Aljamiado scrolls were circulated amongst the Moriscos.
