"Update: Several Egyptian sources are claiming via Twitter that the story below is false. It has been suggested by some that a rumour may have been placed by sources loyal to former dictator Hosni Mubarak. More to follow."
It certainly seems plausible for it to be an intentional rumor. Having said that, I can't see myself believing in the original article in the first place if it weren't for the fact that quite attrocious laws/fatwas actually exist - for example, the infamous adult breast feeding fatwa in KSA.
