The treatise entitled aṭ-Ṭibb ar-rūḥānī bi-l-Qurʾān ar-raḥmānī ("Spiritual Medicine with the Help of the Qurʾān Revealed by the Merciful") is a magical treatise falsely attributed to Ibn Arfaʿ Raʾs.
Carl Brockelmann seems to have been the first to name Ibn Arfaʿ Raʾs as the author of this text. However, as far as the version handed down to us is concerned, it clearly must have been written by someone who lived after Ibn Arfaʿ Raʾs, since it is partially based on Pseudo-al-Būnī's Šams al-maʿārif (written between 670/1272 and the late fourteenth/eighteenth century) and Ibn Sabʿīn's writings (died between 668/1269 and 669/1271).
