I do not know what they tell you in the mosque but I have seen hundreds of messages of Rediff itself to form my own opinion. And the funniest part is that the so-called religious persons (irrespective of religion) do not have any hesitation in ridiculing the "gods" of other religions.
You know the "gods" of all other religins are false. Then what makes you think that your "god" is true? Has any one come back after death to tell the stories in heaven/hell?
