So according to what U wrote, it is either haram or makruh, right? NOTHING ELSE.
Let's use an example:
Hydrogen Cyanide kills within 1 hour, bi iznillah
Gaseous Chlorine may take longer, bi iznillah.
Are you now going to argue about the duration of time it takes before a person dies???
Isn't it the same thing over with the beard thing - it's either makruh or Haram!
Btw tell us one thing Shaykh Isa, what is the ruling of doing a makruh act in the shaf'i madhdhab?
Uhm I don't think that mentioning the Shafi'i position regarding trimming the beard as makruh means condoning the act or even worse calling towards it...
