We need a "Top 10 excuses men give why they do not wear the beard" Or maybe why they wear silk ties, why they wear their pants beneath their ankles, why they wear tight clothing.
As the wearer of a full leyha I would agree with this. I've had a lot of pushback from my brothers who wear nothing but the "line beard" (that has a much nastier name that I won't put here), the beard worn just for fashion, or go smooth faced because "We're still young!" they say. In many societies - even in Muslim countries the full beard is only for elders or scholars. I only know one brother under the age of 30 with a full beard. I'm not talking about the delicate GQ line beard, or the odd jagged lightning shaped beard that so many brothers show up at the masjid wearing...I'm talking a beard you can run your fingers through.
Yesterday when I attended Eid salaat I was wearing a white thobe and full shmaug (a nice white one I obtained in Kuwait) and igal. I had the shmaug thrown back and one brother sitting next to me said "You look like an Emirati". My Saudi friend's reply to that was "No, you would never see an Emirati with a beard".
I know Moroccan brothers who grow a beard here in the US but shave it when they return home to visit.
I have a Tunisian brother at my mosque who says a lehya is illegal in Tunisia.
Our shaykh, who has left us to return to his family in Jordan, would constantly remind the brothers at my masjid not to wear tight clothing, yet so many of them would wear pants so tight you can count the change in their pockets.
So...yeah. The sister's idea is a valid one!
