I'm just curious, is there even a grain of truth to what this person is saying about a girl not being allowed to wear a hijab, or was it just invented from whole cloth?

Probably not. He is a Saudi, after all.

Excerpted from: Student's family sues Oklahoma district over head scarf

A Virginia-based civil liberties group has filed suit against the Muskogee school district for not allowing an 11-year-old Muslim girl to wear a religious head scarf or hijab....
Over the summer, Nashala Hearn started wearing her hijab out of a religious requirement, she said. The girl converted to Islam a year ago....
School officials said the head covering violated their dress code that bars wearing bandanas, hats, caps or other headwear in the school building.
The dress code was developed to curb gang-related activity, according to the school.

A 10-year-old kid converting to Islam sounds a bit unusual to me.
But I can also understand the school's dress code if they've had problems with gang-related violence.

I guess what we actually need to see is a picture.
Something on which to judge whether this is actually religious apparel or some kind of gang-related bandana being flaunted to taunt the authorities.
