Study the incident about Magat and Magachina, The Jawi scripts were used in Borneo and only certain parts of the Philippines … why? Study about the time frame and the prevailing Islamic influences, religion and practices. As a person who studied law, a little knowledge may actually be harmful. As a person who studied law, you should look at ALL aspects before you can say that has no basis to say that so many scrolls were destroyed.
