Ahmed ibn al-Mubarak al-Sijilmasi al-Lamati (1679-1743) was the author of Kitab Ad-Dahab al-ibriz min kalam sayyidi Abdellaziz. It was written in 1717.
This work, commonly known as the Ibriz, is the main source for the teachings of the Moroccan sufi Abd al Aziz al-Dabbagh (died 1719). Al-Dabbagh was an important figure in the tariqa Muhamadiyya.
