Safi al-Din Ahmad ibn Muhammad al-Dajani al-Qushashi (Arabic: صفي الدين أحمد بن محمد الدَّجاني القُشاشي ,1583-1661) was a prominent Sufi master (murshid) of the Shattariyya order, who was born in Medina in 991 Hijri, or 1538 CE.
After returning to Medina, he studied the Shattariyya order from Ahmad al-Shinnawi, who later also became his father-in-law.
After Al-Shinnawi died, Al-Qushashi became his successor in teaching the Shattariyya order in Madina.
[1][2] Al-Qushashi taught the order in a more Sharia-oriented nature and rejected the wahdat al-wujud teaching.
Thus, the dissemination of the Shattariya order by Al-Qushashi students also brought a more orthodox Sufism as their teacher.
