In the Muslim world, it is very popular to call the teachings of the religion a science. As we all know, the God and resurrection cannot be proven or rejected in a lab or through scientific methods. Therefore, is it acceptable to call teachings such as "How to behave as a Muslim" a science? If not, what should we call them in English?
Okay I'm going to try and put this as neutrally as I can I apologise for any offense. I personally respect the teachings of any faith, but generally from a scientific point of view such material is call mythology. This is not to say that the material recorded is in any way untrue but it does denote material that cannot be date verified because of the way it has been recorded, the bible, the Torah, the Norse Sagas, the Illiad, and the Quran are all like this; some of what is recorded can be verified and some cannot and most importantly they're not told in a completely linear order of timing. This is usually a symptom of oral history or traditions being written down and codified at a later date, this is certainly true of large parts of the bible, the Illiad and the Sagas.
The stories told in such texts are lore.
The rules laid down by religious teachings are either doctrine, dogma, or law depending who you ask.
Hopefully that helps you.
