Sahl al-Tustari
Sahl al-Tustarī (Arabic: سهل التستري) or Sahl Shushtarī (Persian: سهل شوشتری) according to Persian custom, born Abū Muḥammad Sahl ibn ʿAbd Allāh (c.818 CE (203 AH) – c.896 CE (283 AH)), was a Persian Sunni Muslim scholar and early classical Sufi mystic. He founded the Salimiyah Muslim theological school, which was named after his disciple Muhammad ibn Salim.
Tustari is most famous for his controversial claim that “I am the Proof of God for the created beings and I am a proof for the saints (awliya) of my time” and for his well-known Tafsir, a commentary on and interpretation of the Qur’an.
