al-Hallāj, Abu ʾl–Mughīth al-ḥusain b. Mansur
He paid the supreme penalty for his choice. After many years of extensive teaching and travelling throughout Central Asia and India, he was arrested, imprisoned and finally brutally executed in Baghdād. His only work to have survived is Kitāb al-Tawāsīn (902 CE). This contains the famous phrase ʾanaʾ l-Haqq (I am the Truth). It is important to read it in its proper context: ‘If you do not recognize God, at least recognize his signs. I am that sign, I am the Creative Truth (ʿanaʾ l-Haqq) because through the Truth I am a truth eternally.’ (Kitāb al-Tawāsīn, pp. 51–2). Cf. also AL-INSĀN AL-KĀMIL.
