Ṣadr al-Dīn Muḥammad ibn Isḥāq ibn Muḥammad ibn Yūnus Qūnawī [alternatively, Qūnavī, Qūnyawī],, was a Persian philosopher, and one of the most influential thinkers in mystical or Sufi philosophy. He played a pivotal role in the study of knowledge—or epistemology, which in his context referred specifically to the theoretical elaboration of mystical/intellectual insight. He combined a highly original mystic-thinker, Muḥyī al-Dīn Ibn 'Arabī, whose arcane teachings Qūnavī codified and helped incorporate into the burgeoning pre-Ottoman intellectual tradition, on the one hand, with the logical/philosophical innovations of Ibn Sīnā, on the other. Though relatively unfamiliar to Westerners, the spiritual and systematic character of Qūnawī's approach to reasoning, in the broadest sense of the term, has found fertile soil in modern-day Turkey, North Africa and Iran not to mention India, China, the Balkans and elsewhere over the centuries.

Ibn ʿArabī was an Andalusi Arab scholar, mystic, poet, and philosopher, extremely influential within Islamic thought. Out of the 850 works attributed to him, some 700 are authentic while over 400 are still extant. His cosmological teachings became the dominant worldview in many parts of the Muslim world.
