I agree with the points that have been mentioned here. The learning of Arabic is of importance, as is (I believe) reciting in the Arabic languagebut only with understanding.
That is why I am wondering if it is necessary to make recitations in Arabic, as I believe many have been taught. If it is, then there is no debate, but if not I believe it warrants a difference in the way we are guided in our religion. By placing emphasis on the importance of understanding, but of course making clear that Arabic is the only true language of the revelation.
Let me illustrate what I think is a common scenario for those who do not grow up 1) knowing Arabic, or 2) attending an Islamic school. This is also from personal experience. Initally, we are taught the translation of what we are saying in Arabic. But, we are also taught that we must make our salat in Arabic, so we strive to memorize the Arabic. Initially, we know what we are saying and but we are trying hard to commit the Arabic to memory. Then time passes, we are performing Salat easily in Arabic but the meaning has become more general and slightly vague. We forget the distinction between, 'Subhana Rabbi Atheem' and 'Subhana Rabbi'l A'la'. The last 3 ayat of Al-Fatiha become a general concept. And on. Finally we may forget the majority of the prayer all together and we don't realize until we have a shocking moment, when we might make a mistake in the recitation, and think 'Wow, what was I even just saying then!'
It wasn't until I devoted myself to truly studying the Arabic words, meaning by meaning, and conciously performed my salat comparing the Arabic I was speaking to my understanding, did my prayers actually feel fulfilling in the way they are meant to. Even today, when I am a bit more distracted, I will begin to pray in English to focus myself because the understanding of my words is spontaneous. I think back to the years when I was just 'making Salat in Arabic' and I realize why my deen wasn't so strong. The central point of my worship was something that wasn't even understood by me!
Again, I'm not discrediting the importance of knowing Arabic or reciting in Arabic at all. But, I want to highlight the importance of understanding, and promoting understanding first. If there is nothing barring us from reciting in our native language, that should be known and accepted. If it is evidenced that we should only be reciting in Arabic, then we really need to be stepping up our efforts in promoting understanding!
