Rihanna went too far when she dressed up as an Arabian prostitute to mock Islam in the photo above.
Prostitution is a sacred occupation in the Islamic world, and is filled only with decent Allah fearing women who know how to please their Muslim lords. The fact that Rihanna would shame them by pretending to be part of their ranks crosses the line, and is much worse than 9/11.
A fatwa will be issued at noon prayer, calling for Rihanna to be punished for this egregious offense against Islam and our whores. Rest assured the retribution for this crime will be swift and severe. Allahu Akbar!
