Introduction: Two of THE stories mentioned in THE Qur'an are THE story of Adam and THE FORBIDDEN TREE and THE Story of Moses going to THE Right Side of THE Valley and hearing THE TREE. THEse stories are of much interest to THE scholars and mentioned in many of THE mystic texts and commentaries in prose and verse such as Meibodi's Kashaf al-Asrar, Tamhidat of Ein al-Ghozat, works of Ruzbehan Baqli, Shabestari's Golshan-e Raz, Mathnavi of Mowlavi, Mersad al-Ebad of Najm al-Din Razi and many more. THE TREE in both stories is a mystical symbol. In this paper THE symbolic meanings of THEse two TREEs are analyzed and compared.This is a comparative study of two symbols in religious and mystical texts. THE Qur'anic symbol of TREE (FORBIDDEN and Moses') are analyzed. Discussion: In many instances such as verse 35 of Baqara, verse 19 of 'Iraf and verse 12 of Taha, THE Qur'an refers to THE story of Adam and THE FORBIDDEN TREE. Mystics have interpreted THE FORBIDDEN TREE as THE physical world, divine secrets, THE knowledge of destiny and fate, wisdom, love and union.Seid Heidar Amoli considers THE FORBIDDEN TREE THE symbol of THE physical world which will result in leaving THE Garden of Eden. Aziz al-Din Nasafi considers THE FORBIDDEN TREE as THE TREE of wisdom and a reminder of free will; THE result of this free will is doubt and only love of God can free man from doubt. In 'Araes al-Bayan and Sharh-e Shatthiyat Ruzbehan regards THE TREE as THE secret of love. Attar referring to verse 35 of Baqara believes that THE TREE is THE TREE of union. Meibodi says that union as a sign of THE FORBIDDEN TREE also reminds one of THE pain and suffering of proximity.In verse 30 of Qisas THE story of Moses and his departure to THE Right Side of THE Valley is told. THE TREE of Moses has allegorical meanings such as absolute existence, THE sacred soul of man, THE light of Mohammad (PBUH), THE power of thinking, love, knowledge, monoTHEism and union. Seid Heidar Amoli and Ruzbehan consider THE TREE of Moses as THE absolute existence.Conclusion: Revelation has descended in a multidimensional language. Mystics have interpreted Qur'anic stories from different points of view due to THEir allegorical meanings. Interpretations of THE mystics show that THE FORBIDDEN TREE means love and THE TREE of Moses means THE sacred soul of man. According to mystics THEse stories are abstract concepts such as love, wisdom, knowledge and union. Different intuitions, mystical experiences and interpretation of Qur'anic verses by different mystics have led to a rich body of literature which testifies to THE still hidden meanings of THE Divine subject.
