Re: Shaving the beard or mustache.. ?
A case can be made about not observing any sunnuh, fards or wajib, by stating that....oh I don't pray, so I might as well not eat halal either.....I don't do namaz so I should not observe the attiquettes of islamic dressing.....I will stop zina when I start praying, otherwise I will continue to do it....
One action or lack thereof, should not prevent one from observing others.......
