Following the attack on a Sufi mosque in Egypt, which left over 300 dead, many are asking what Sufism is and why Sufi Muslims were targeted for attack. In this piece in Vox, Imam Feisal explains that Sufism is “the core and the very spirit of Islam itself… The essence of Sufism is teaching people how to see God.” Sufis are targeted by extremists because many extremists wrongly believe that Sufis are not “true Muslims.”
