The 177-verse Arabic Poem of the Intellect (Qaṣīdat al-ʿAql) composed by the Indian Fatimid-Ṭayyibī Dāʿī al-Muṭlaq Sayyidna Taher Saifuddin (d. 1385/1965) breaks new ground in substance and form. In form, the poem creatively amalgamates the genres of qaṣīdah (poem), risālah (treatise), and waṣiyyah (testament) to produce an eloquent and innovative hybrid text. In content, it uniquely combines a philosophical exposition on Islamic theology and ethics with a road map to living a Pure Life. After an opening frame that provides a philosophical foundation, the poem’s three large thematic sections draw on the Qurʾan, the Prophet’s Hadith, and the sermons of Imam ʿAlī to describe principles of belief and approach, articles of character and deeds, and the grounding of both—abstract philosophy and concrete instructions—in love for and allegiance to the divine guides, the Imams and Dāʿīs, who are “God’s rope.” It has a gentle tone, preaching harmony between all people on earth, tranquility in one’s life, cheerfulness and positivity, and an atmosphere of love and caring. The closing section brings the poet directly into the frame of reference, stating that he, as the incumbent Dāʿī, is himself the manifestation of God’s rope in the current time, and those who follow his guidance will return to Paradise. The present article provides a window into Sayyidna Taher Saifuddin’s remarkable poem, translating and analyzing it against the backdrop of Fatimid and Ṭayyibī theological works and, briefly, the colonial and post-colonial fabric of early 20th century India, to explore a significant and largely unknown chapter of Arabic poetry.
