Re: Miswaak and its Benefits
^
Miswaak similarily has the same benefit, of cleaning and spiritual. Tootbrush you can use ofcourse, but it'll only get your cleaning done. And you might get sawaab for being clean, just like you would get sawab for say praying at home. If you pray at a masjid with congregation, you get more sawaab. If you clean with miswaak you'll get more sawab.
Perhaps the rule is different for women since they are encouraged to not pray at the masjid with congregation. They either don't need the extra sawaab, don't deserve the extra sawaab or get it from somewhere else. Maybe the same with miswaak.
