If you are getting emails from your friends with a report by UNESCO that declares that "Islam is the most peaceful religion", relax. It's all a big spoof complete with certificate and all.
Apparently, the spoof originated here.
Even UNESCO was quick to issue a denial.
Of course, given UNESCO's dubious history, one can understand why some people might think it's a real story.
Notwithstanding the clarification, some people still think it's real, like Pope Francis the First (and hopefully the Last).
