Do Sufis believe in hijab?
In Sufism, the Hijab (Arabic: حِجَاب) is the divine veil that covers the qalb (heart) of the murid (a novice committed to spiritual enlightenment) before reaching the maqāmāt (stages) of the tajalli (disclosure of God as truth) and nūr manifestation (Light of God) of Allah's mercy. It is not a physical entity.
A lot of terrorist Muslims will claim to be Sufis or some other version of Islam marketed as being 'peaceful n stuff'. The Koran tells them to lie to infidels whenever it furthers their cause. Read up on 'taqiyya' and re the Koran read up on abrogation and how that works. Never ever believe anything a Muslims says to you about Islam being 'peaceful'; none of it is. Just assume everything they say is a lie, and you will be right at least 90% of the time.
