Abu al-Mughith al-Husayn ibn Mansur al-Hallaj, b. 858 in Tur, Iran and d. March 26, 922, Baghdad, was a controversial sufi. He won the admiration of many Muslims and the ire of the orthodox jurists. He learnt under many famous sufis. From 895-910 A.D., he travelled extensively and taught and wrote. He who went further than al-Junayd in his ideas of union with God and claimed "I am the Truth" (Ana al-haqq). This claim landed him into trouble and he was crucified as a heretic and brutally tortured by orthodox Muslims in Baghdad. At his death, he uttered words of forgiveness for his torturers.

By the same token, Jesus would be condemned as a heretic by orthodox Muslims, for he said :

Jesus said to him : I am the Way, the Truth and the Life. No one comes to the Father but by me. (John 14:6)
