"Major ideas in Sufi metaphysics have surrounded the concept of wa\u1E25dah (meaning \"unity\"). Two main Sufi philosophies prevail on this controversial topic. wa\u1E25dat al-wuj\u016Bd literally means the \"Unity of Existence\". On the other hand, wa\u1E25dat ash-shuh\u016Bd, meaning \"Apparentism\" or \"Unity of Witness\", holds that God and his creation are entirely separate."@en .
