Not sure but I don't really think she became agnostic. I think she just didn't believe in the Koran. Her parents are Muslims though.
i don't believe in religion but i want to believe in a god but at the same time i don't. but my family don't know i left the religion. they know i don't practice it and often my mum equates that to not being a muslim at all. but she uses it in an offensive way... which doesn't bother me at all...
