assalamu aleikum, i heard a lot of women believe Allah told us to cover only our hair, so they wear a turban instead of a full hair, chest and neck covering hijab. do you know which texts these people follow?
Alaikumassalam wa rahmatullah,
I know of no respectable scholar who permits showing the neck. As far as I know such people are following their own personal preferences. For more on the evidence for the hijab as it is worn by mainstream, conservative Muslims see: Why the hijab is still obligatory (and why it is not only a vestige of 7th century Arabia)
