Why should one be muslim ?

Everyones experience is different, to why they come to religion, some people base their faith on the scientific miracles of the Quran, where as others to Moral side of it etc, but at the root we all beleive theirs no God But Allah and Muhammed s.a.w is his Messenger, i dont know what other faith can be more simple then this. And why those it matter, because faith is an "individual" thing, we all have different aspects of Islam that we love, even during reckoning, different people will be sent to heaven for different reasons, some for fasting, some for being patient, some for praying, educating others etc.

And regarding your point of being brought up into a Chinese or lets say a Buddhist family, obviously your inclinations will be more biased to that faith, but at the end of it, faith is not something the society you are brought up in determine, one can go to pray in church or mosque because everyone else closes their shops, but might not have "faith" if you know what i mean.

Also, about understanding Arabic to understand the Quran, i think, we have been blessed with a translations now, but over the 100s of years, people were without these, and the man in China did rely on his Chinese Imam to "translate" the religion for him in regards to maybe deeper issues.

When the early Muslims spread across the world, they did not stuff Arabic texts into the non Arabs faces, it was through their actions that many accepted Islam.

Obvoiusly, we are told to read the Quran in Arabic because it is the word of god and thier is benefit in doing so, we are not told to read other Arabic books to be a better Muslim or unlike some people like to beg and think, it is not a "condition" to learn Arabic, understanding Islam as a whole would not be through such. Otherwise all the Non Arab Muslims are condemned to hell lol.

But if you pick up any medical, maths, philisphy book, will only fool yourself if you think you understand the subject without any "background" in the technical words used in whatever contexts, wont try to should like a smart ass here but yeah, hope you understand.

I dont think you should let Polarize religion in such way and make it difficult for yourself.
