There are two places for an atheist in sharia communities: the closet or the grave

Renouncing Islam and embracing atheism is like passing a death sentence on oneself. Renouncing Islam is apostasy, and apostasy is a crime punishable by death. Expressing atheistic views can easily be interpreted as a form of blasphemy. Blasphemy is a crime punishable by death. Expressing atheistic views can easily be taken to be an insult to Islam or to Allah or to his Prophet Muhammed. Islam may mean peace for Muslim faithfuls, but for atheists it means war. The Islamic establishment is engaged in a constant battle against infidels and unbelievers. It has no humanly dignified and respectable space for atheists and godless people.
