It is something which i find unnatural. Most of the Muslims around the world don't know Arabic. The national language of Pakistan is Urdu, and i can safely say about 90% of Pakistani muslims don't know Arabic. I have met many people who don't know what they are saying in Namaz, what they are reading in Quran, what is the meanings of different duas they have learnt. People are just going through the motions without knowing what they are saying or reading. The most surprising thing is the acceptance of this ignorant attitude. No one finds it odd. Doing important functions without understanding just makes it a robotic ritual, it diminishes spirituality and creates distance b/w man & religion.
The solution given is learn Arabic, learn the translation, read the tafsir. Keeping in mind the literacy rate of the country is around 40%, and that most of the masses are busy in making ends meet, expecting the population to learn Arabic is like asking for the moon. It may work for some individuals, but not for the masses.
Why not just pray in Urdu, why not start teaching the Quran in Urdu. Instead of expecting people to learn or memorize Arabic, why not make religion easy for the masses. Take it to a level that even an illiterate person can understand and relate to his actions. Why insist on Arabic.
