Rabia Basri

Rābiʼa al-ʼAdawiyya al-Qaysiyya (Arabic: رابعة العدوية القيسية; c. 716 – 801 CE) or Rabia Basri was a poet, one of the earliest Sufi mystics and an influential religious figure from Iraq. Her full name is said to be Rābiʿa bint Ismāʿīl; her kunya was Umm ʿAmr (or Umm al-Khayr), her wilāya was al-ʿAtakiyyah, and her nisba was al-ʿAdawiyya or al-Qaysīyya because she was a freed slave of the tribe of Qays ibn ʿAdī. She is regarded as one of the three preeminent Qalandars of the world.
