I have a few Kurdish friends ( most of them having escaped from Iraq and Turkey ).
While they call themselves Muslim, my impression is most Kurds do not consider themselves particularly religious when it comes to adhering to the call to prayer five times a day. They adhere to Islam only as a cultural thing.
A minority of Kurds, primarily in the Nineveh Province of Iraq, follow the Yazidism.
Yazidism combines complex Kurdish cultural beliefs with Zoroastrianism and Islamic Sufi doctrine.
It applies traditions of the Abrahamic religions such as the story of Adam and Eve, the importance of pilgrimage, and daily prayer ritual, to more mystical elements, focusing on the importance of ancestry and the four elements on the Earth.
The religion is practiced in the Kurdish dialect of northern Iraqi Kurdistan, Kirmaji.
To make a long story short.... the further they are from adhering to the strict tenets of the Koran, the BETTER they will be.
The Kurds in the Nashville area don’t appear particularly devout religious, either. Their women tend to dress like modest western women.
