Dhu'l-Nun al-Misri

Dhū'l-Nūn al-Miṣrī (d. Giza, 859-862), often rendered in English literature as Dhū'n-Nūn al-Miṣrī or Zūl-Nūn al-Miṣrī, was an early Egyptian Sufi mystic and alchemist. His surname al-Miṣrī means "the Egyptian".

He was born in Akhmim, Upper Egypt in 796 and is said to be of Nubian descent. Dhu'l-Nun is said to have made some study of the scholastic disciplines of alchemy, medicine, and Greek philosophy in his early life, before coming under the mentorship of the mystic Saʿdūn of Cairo, who is described in traditional accounts of Dhu'l-Nun's life as both "his teacher and spiritual director."

Celebrated for his legendary wisdom both in his own life and by later Islamic thinkers, Dhu'l-Nun has been venerated as one of the greatest saints of the early era of Sufism.
