HB: Knowing the rituals does not constitute understanding islam. Executing the rituals, does not equate understanding of islam. For a non-arab to know how to state some Arabic words like "Insha-alla or Masha-alla or iman or kufr or fiqh or sunna or hudud or hamadnak" that does not constitute understanding of islam.
Elle: Yes you can be a muslim without following the koran. Yes you can be a muslim without understanding islam. Yes you can be a muslim while ignoring islamic rules. Sit back and deal with this concept as you are not doing anyone a favor.
People like you holding this wide brush that are making it very hard for me to discuss islam on an intellectual level with western soon-to-be-dhimmis. Those dhimmis listen to you painting everything with this wide brush and think to themselves, holy crap, the muslims have lunatics coming after them. And they will oppose you and ban you just to spite you. But worse for me, they will become super-defensive.
Using the Arabic words like Inshallah or Mashallah even when you're not Arabic doesn't mean you don't understand the words. People can be multi-lingual you know. Even if you aren't multi-lingual, I'm sure you will know what it means if someone comes up to you and says "Hola" or "Bonjour".
Mashallah and Inshallah are common words used in Islam.
I'm not saying it constitutes understanding Islam, I'm saying that I know people who follow Islam inside out. They practice it by the book, so to speak.
There are Muslims who don't follow the Quran sunnah to sunnah, of course. But there are those who do follow it rule to rule.
You say executing the rules does not constitute understanding Islam, so then what does? What does one have to do/say to prove that they do actually understand the religion??
