Salams
I know this isn’t theoretical but I wanted to know some answers for my ?s.
What better place than gupp shuppJ

  1. Has anyone heard that HALLALEUAH is the latinization of YA ALLAH HOO?
    ALLAH HOO YA don’t you see it being possible?

  2. Do you know how the crescent and star and the color green became symbols of Islam.

  3. Also has anyone heard that the cap used in university graduations are from Muslims theology students who would place the Quran on their heads tied with a scarf. I heard it was started from the grand mosque in cairo, I forgot the name but its one of the largest Muslim religious/ theology universities.

Thanks

Reagrding your third question, is it Jama'-e-alazhar?

Also, you might want to check your sources regarding question 1 and 3. Question 2 sounds pretty interesting. Let's see if we can get some good info. about that from other participants.
