Sufi Scholars

Imam Abu Hanifa (85 H. - 150 H)

"If it were not for two years, I would have perished." He said, "for two years I accompanied Sayyidina Ja'far as-Sadiq and I acquired the spiritual knowledge that made me a gnostic in the Way." [Ad-Durr al-Mukhtar, vol 1. p. 43]
Imam Malik (95 H. - 179 H.)

"whoever studies Jurisprudence [tafaqaha] and didn't study Sufism [tasawwaf] will be corrupted; and whoever studied Sufism and didn't study Jurisprudence will become a heretic; and whoever combined both will reach the Truth." ['Ali al-Adawi , vol. 2, p 195.]
Imam Shafi'i (150 - 205 AH.)

"I accompanied the Sufi people and I received from them three knowledges: ...how to speak; how to treat people with leniency and a soft heart... and they... guided me in the ways of Sufism." [Kashf al-Khafa, 'Ajluni, vol. 1, p 341.]
Imam Ahmad bin Hanbal (164 - 241 AH.)

"O my son, you have to sit with the People of Sufism, because they are like a fountain of knowledge and they keep the Remembrance of Allah in their hearts. they are the ascetics and they have the most spiritual power." [Tanwir al-Qulub p. 405]
Imam Ghazzali (450 - 505 AH.)

"I knew verily that Sufis are the seekers in Allah's Way, and their conduct is the best conduct, and their way is the best way, and their manners are the most sanctified. They have cleaned their hearts from other than Allah and they have made them as pathways for rivers to run receiving knowledge of the Divine Presence." [al-Munqidh, p. 131].
