Ibn Abbad al-Rundi (Arabic: ابن عباد الرندي) (in full, Abu 'abd Allah Muhammad Ibn Abi Ishaq Ibrahim An-nafzi Al-himyari Ar-rundi) (1333–1390) was one of the leading Sufi theologians of his time who was born in Ronda. Attracted to Morocco by the famous madrasahs, Ibn Abbad emigrated there at an early age. He spent most of his life in Morocco, living in different cities (Salé, Marrakesh, Fes...), and was buried in Bab al-Futuh (south-eastern gate) cemetery in Fes.
