According to religious teachings, religious rites and rituals, in addition to their external image, possess an internal image which creates Man’s identity and soul. In Islamic traditions, several works have been written on the secrets of Sharīa‘ah, some of which discuss them in general and some analyze specific rites and rituals. In this regard, reference can be made to al-Futūḥāt al-makkīyyah by Ibn ‘Arabī, Asrār al-sharī‘ah wa aṭwār al-tarīqah wal-ḥaqīqah by Sayyid Haydar Amuli, Mahajjat-al-bayḍā by Mullā Muḥsin Fayḍ Kāshānī, treatise of al-Tanbihāt al-‘aliyyah ala waza’if al-ṣalāt al-qalbīyyah by Shahīd Thānī, and Asrār al-ṣalāt by Imam Khomeini. In two parts of the book al-Shawāhid al-rubūbīyyah fil manahij al-sulukīyyah, Mullā Ṣadrā has also discussed the secrets of Sharī‘ah. The present paper investigates and analyses his views regarding the secrets of Sharī‘ah.
