Mansur al-Hallaj is born
Mansur al-Hallaj (Persian: منصور حلاج - Mansūr-e Hallāj; Arabic: منصور الحلاج - Mansūr al-Hallāj; full name Abū al-Mughīth Husayn Mansūr al-Hallāj) (c. 858 - March 26, 922) (Hijri c. 244 AH-309 AH) was a Persian mystic, revolutionary writer and pious teacher of Sufism most famous for his apparent, but disputed, self-proclaimed divinity, his poetry and for his execution for heresy at the orders of the Abbasid Caliph Al-Muqtadir after a long, drawn-out investigation.
If you do not recognize God, at least recognise His sign, I am the creative truth - Ana al-Haqq -, because through the truth, I am eternal truth. My friends and teachers are Iblis (Satan) and Pharaoh.”— Al-Hallaj
People imagine that it is a presumptive claim, whereas it is really a presumptive claim to say "I am the slave of God"; and "I am God" is an expression of great humility. The man who says "I am the slave of God" affirms two existences, his own and God's, but he that says "I am God" has made himself non-existent and has given himself up and says "I am God," that is, "I am naught, He is all; there is no being but God's." This is the extreme of humility and self-abasement.”— Rumi on the claim "I am God"
