Mansur al-Hallaj was a Persian mystic who preached publicly in Baghdad, which was already unusual, and who is reported to have said ana al-Haqq — I am the Truth, al-Haqq being one of the names of God. After long imprisonment and a trial with political dimensions involving the Abbasid court, he was executed in 922, brutally and in public. The Sufi reading is that in the state of fana the speaker has been annihilated and it is not the man speaking; the juristic reading is that this is blasphemy however it is glossed, and a number of Sufis including Junayd distanced themselves at the time. He became the tradition's permanent test case for how far interior experience may be said aloud, and the standard Sufi conclusion was discretion rather than agreement — the sober path of Junayd was recommended precisely because Hallaj's was not survivable. He is now quoted with reverence in poetry from Persia to Punjab to Java, including by people whose own legal school would have upheld the sentence. Attar, Rumi and Iqbal all wrote about him.
