The main rule of writing is that if you do it with enough assurance and confidence, you're allowed to do whatever you like. So write your story as it needs to be written. Write it honestly, and tell it as best you can. I'm not sure that there are any other rules. Not ones that matter. ~ Neil Gaiman
Well said by the previous pinner: Why is it that overtly religious, Islamic or Christian, feel they need to have everyone follow just "their" religion. That it's not enough that they follow their religious requirements but they must force everyone else to as well.
