Sadr al-Din al-Qunawi

Ṣadr al-Dīn Muḥammad ibn Isḥāq ibn Muḥammad ibn Yūnus Qūnawī, (Persian: صدر الدین قونوی; 1207–1274), was a philosopher. He was a notable contributor to mystical or Sufi philosophy (which is closely aligned with metaphysics) and influenced the philosophical study of knowledge, epistemology, specifically in reference to the theoretical elaboration of mystical/intellectual insight. He combined the works of mystic-thinker, Muḥyī al-Dīn Ibn 'Arabī (1165-1240 CE/560-638 AH), and the logical/philosophical innovations of Ibn Sīnā (Lat., Avicenna), on the other.
