Banning female genital mutliation

Finally, Islamic scholars and national figures in Mauritania signed a fatwa to ban female genital mutilation.
"There's no doubt that the fatwa will substantially curb [FGM], since it removes the religious mask such practices were hiding behind."

Thank goodness for some sense. It may have taken them a long time to get there, but they did. I'm not familiar with how far-reaching fatwas are. This was done in Mauritania, does it mean all Muslims will follow it?
