Q: Is it permissible for a lady, to perform Salaah with a see-through scarf or burqa?
A: Salaah performed with a scarf or burqa through which a lady’s hair or/and skin is visible, is not permissible.
Hadhrat Aaisha (Radiyallahu Anha) was once asked about the scarf of a woman. She replied that the scarf should conceal the skin and the entire hair of a woman.
