Notable Sufi works Among the most popular Sufi works are: (The Exploration of the Path of Sufis) by Abu Bakr al-Kalabadhi (d. ca. 380/990), a popular text about which 'Umar al-Suhrawardi (d. 632/1234) is reported to have said: “if it were not for the Ta'arruf, we would know nothing about Sufism”. (Nourishment of the Hearts) by Abu Talib al-Makki (d. 386/996), an encyclopedic manual of Sufism (Islamic mystical teachings), which would have a significant influence on al-Ghazali's Ihya' 'Ulum al-Din (The Revival of the Religious Sciences).
