The Malāmatiyya (ملامتية) or Malamatis were a Muslim mystic group active in 9th century Greater Khorasan. Their root word of their name is the Arabic word malāmah (ملامة) "blame". The Malamatiyya believed in the value of self-blame, that piety should be a private matter and that being held in good esteem would lead to worldly attachment. They concealed their knowledge and made sure their faults would be known, reminding them of their imperfection. The Malamati is one for whom the doctrine of "spiritual states" is fraught with subtle deceptions of the most despicable kind; he despises personal piety, not because he is focused on the perceptions or reactions of people, but as a consistent involuntary witness of his own "pious hypocrisy".
"Malamati" can also refer to a method of teaching within Sufism based on taking blame.
The Malamati originates in a town called Nishapur in Khorasan in the ninth and tenth centuries. Nishapur was one of the four main towns in Greater Khorasan and it was at the crossroads of two main routes. Because of their distance from Baghdad, the Malamatiyyah originally had very little influence from Sufi practice and thought.
The Malamati mystical movement developed independently from Sufism until the Baghdadi and Khurasani mystical schools combined. With the rise in Sufi literature and the stature of Baghdad as an intellectual community during the late tenth century, Sufi became the umbrella term for all Muslim mystics. The name Malamati slowly disappeared as the term Sufi was used with increasing frequency although the Malamatiyyas had their own distinct practice and ideology. In fact, some sources claim that the Malamati path was heterodox to Sufism and that the two schools of thought are incompatible. Some even claim that the Malamatiyyas are not only separate from Sufism, but also from Islam. Malamati critics say that the Malamatiyyas are not completely Muslim in "spirit or in theory".
The Malāmatiyya were first written about by Abu ‘Abd al-Rahman al-Sulamī (d. 1021) in the 11th century AD (4th–5th century AH). Al-Sulami was born in Nishapur in 937 to a prestigious family. His father was on good terms with the early Malamatiyya. When al-Sulami was young his father moved to Makka and left al-Sulami under the care of his maternal grandfather. His grandfather, Abu ‘Amr Isma’il b. Nujayd al-Sulami (d. 971) was the spiritual heir to Abu ‘Uthman al-Hiri (d.910) who is an important figure in the formation of the Malamatiyya.
