That is ur belief. To rest of the world, Mohammad makes no sense. So, it is best not criticise. All religions have strong points and negatives. If Hindu religion has survived more than 10000 years, there must be strength init which u donot understand. If Christians worship jesus even today, there must have been miracles that you are unaware of. If god or Allah wanted only one religion to survive, it would have been a fact long ago. But all religions are surviving & growing. They are like a circle whose all radii meet in the centre. Spread love. Ego is the cause of every problem. When u say ur religion is only right then u create a problem. My religion is as good as urs. But it is a personal matter. I do not get it into business or my dealings with other. This is where muslims falter and suffer.
