Bismillah
As Salam alaikum
It clearly marks where the muslims are gathering in a crowd.
I was looking for the my Muslim Student Organization table today when all of the clubs and groups get together on campus to introduce themselves to the student body, especially new comers. I walked around the area twice and still could not find it. I called the president, no not Bush, and asked him where the table was. I still could not find it but the directions made me look in the right direction. I saw a brown hijab and knew where I had to go.
Alhamdulillah for hijabs
ps I would not marry a woman without a hijab either.
As Salam alaikum wa rahmatullahi wa barakatu
