Pl. of ḥaqīqa. A system originating in 9th-century Ismaili texts, and later modified and developed in a Neoplatonic framework by al-Nasafī (d. 943), Abū Ḥātim al-Rāzī (d. 934), Abū Yaʿqūb al-Sijistānī (d. ca. 971) and Ḥamīd al-Dīn al-Kirmānī (d. after 1020) in the 10th and 11th centuries. According to these authors, behind the external aspect (ẓāhir) of religious prescriptions, which can change with every prophet, the ḥaqāʾiq are the immutable and eternal truths of the realm of the bāṭin (the hidden), which are known to the Imam and accessible only to the initiated or the elite.
