Anchal:
You are right on the fact that we shouldn't judge other peoples prayers, however it is our duty to help them understand the importance of prayer.
When we confront Allah we do two of the following things:
1) Praise Him
2) Ask Him
Ok, os let me put a LOT of emphasis on this:
Allah need ** no ** praise, for He is above all praise, our praise will not glorify Him any further, for His glory is limitless.
Allah also needs ** no ** petition, for He, the All-Knowing know our needs better than we do; His bounties are open without asking, both to the righteous and the sinner.
Islam is not just a religion, it is a way of life. In reality, it is the * perfect * way of life. The Quran is one of the greatest gifts of Allah. Having a perfect, peaceful and prosperous life is only good for our own spiritual well-being.
If you go back a few centuries to the great Islamic days, where everybody practicised the right deen you will understand that Allah did not benefit from there righteousness, but they themselves benefitted. That was the age when most people had perfect lifestyles, when arts and science flourished and when there was peace, brotherliness and friendliness. You will realize that just being a good person is not enough.
A recent study has revealed that the optimum fasting needed by the body to clear up the digestive system is around 30 days. and lo!, Islam has prescribed 30 days fasting for us already.
I believe, that Namaz helps remind us that we have to abide by the laws of Islam and be nice to other people and most of all be nice to ourselves.
Being ungrateful to His favors, and defying Him will not hurt Him in any way but will hurt ourselves and our community.
Islam is not a law that has to be enforced, it is a teaching, we follow it our your own good, if we don't there should be no compulsion. The verse of the holy Quran taken right after the Ayaat-al-kursi in Surah al Baqarah says it all:
"Let there be no compulsion in religion, Truth stand clear from error" [2:256 Holy Quran]
Being a good person is nice, but along with that we also have to understand the meaning of this life. We should pass this test and win the super life afterwards! I mean how could we be defiant of our own Creaator, its just so rude.
