“I have seen my Lord with the eye of my heart, and I said: ‘Who are You?’ He said: ‘You.’"
-- Mansur Al-Hallaj
Mansur Al-Hallaj was one of the most controversial Sufis in the history of Sufism. He was brutally tortured and executed for saying, "Ana al Haq" which means "I am God" or "I am the truth".
