As an atheist, I question the superstitions in all faiths. You have seen the messages posted by an article on Rediff written by Sri Sri Ravi Shankar.
Why are we fighting in the name of non-existent gods and so-called holy books created by surrealistic visionaries? The Islamic Paradise existed only in the fertile imagination of Moahmmed. Don't blow yourself up in the hope of getting those rewards in the "life here-after" nor harm others!
Life on planet earth is the only thing known to us. Enjoy the same to the extent possible, without creating any problem for others.
