In most non-Arab Muslim countries, even though Islam is a very strong and important part of their culture, Arabic is not recognized or used by the general population. While I understand its not necessary for someone to know Arabic to be a Muslim, considering how everything in Islam is based off Arabic, I'm surprised its not used more outside of religion. For example Indonesia, Pakistan, and Bangladesh are all non-Arab Muslim majority countries. They each speak Bahasa Indonesian, Urdu, and Bengali as their primary language. They don't even speak Arabic as a second language either. Those countries have English and Dutch as their primary second language. That's understandable. As those are the languages of the countries that used to rule them. All these countries, while diverse, have cultures very strongly connected with Islam (Note: I know not everyone in those countries is Muslim and all those countries have various diverse cultures that may or may not have Islamic influences. But the mainstream culture of these countries is still very influenced by Islam). Yet despite their cultures' ties with Islam, they do not seem to use Arabic at all outside of religion. I would like to know Arabic isn't a bigger part of those countries. Also, feel free to correct me on any mistakes or inaccuracies in my statements. I'm always willing to learn.
