Seriously? How are they Khawarij when Al-Azhar, the largest Muslim beacon, blatantly refused to deem them as Khawarij or Infidels?
So forcing women to wear niqabs is an act of Khawarij? The Islamic State is the authority, therefore their job is to enforce Shari’a law. Shari’a law stipulates that women HAVE to cover their faces and dress modestly. It’s fard, not something that should be defied by any pious Muslimah. You should be ashamed of yourself.
“The woman’s dress as prescribed in sharee’ah (“Islamic dress”) is that which covers her head, face and all of her body.”
