Sahl al-Tustari سهل بن عبد الله التستري

Sahl ibn Abd Allah al-Tustari rahimahullah (c.818-896 CE / 203-283 AH), also known by his kunya Abu Muhammad, was a Persian Muslim scholar and one of the foremost figures of early classical Sufism. Born in Tustar (in present-day southwestern Iran), he founded the Salimiyya theological school, which took its name from his disciple Muhammad ibn Salim. Al-Tustari is most celebrated for his Tafsir, a commentary on and interpretation of the Qur'an, which stands as one of the earliest extant Sufi commentaries on the Qur'an. He was known for his ascetic discipline, his deep engagement with the spiritual dimensions of Qur'anic meaning, and his influential teachings, which profoundly shaped the subsequent development of Islamic mysticism.
