The Fifth FISLI Discipline
Manṭiq: Teaching Islamic Logic in the Muslim School
Allah commands afalā taʿqilūn — "will you not reason?" — forty-nine times in His Book. The classical tradition built an entire science around that command. We built the curriculum to teach it.
What Is Manṭiq?
Manṭiq is the Arabic term for logic — the science of correct reasoning. The word derives from the root n-ṭ-q, meaning to speak, to articulate what the mind has grasped. In the classical Islamic scholarly tradition, Manṭiq was not considered philosophy. It was considered a tool — the instrument that makes every other Islamic discipline intelligible.
Al-Ghazālī, one of the greatest theologians in Islamic history, identified thirty valid syllogistic forms in the Qurʾān before any European logician had named them. The classical tradition built an entire science around the Qurʾānic command to reason. The FISLI curriculum restores that science to the Muslim school.
Why Classical Scholars Required Manṭiq
In the classical madrasa sequence, students did not study Manṭiq first — they studied it last. This was deliberate. Manṭiq was placed last because its function is retrospective: the student who studies Manṭiq after Sīrah, ʿAqīdah, Ḥadīth, and ʿUlūm al-Qurʾān discovers that she has been doing Manṭiq all along and can now name and sharpen what she has been practicing.
A student who has absorbed the five FISLI disciplines in sequence arrives at Manṭiq not as a stranger but as someone coming home to the name of something she already knows. That is why FISLI sequences Manṭiq fifth — not because it is least important, but because it is most powerful when it arrives last.
The Classical Sources
The FISLI Manṭiq curriculum is anchored in two primary classical texts that have been used in Islamic seminaries for centuries:
Al-Sullam al-Munawraq
By Al-Akhḍarī (1515–1584). The most widely studied introductory logic text in the classical Arabic Islamic tradition. A 144-verse poem covering the fundamentals of logic from concept to syllogism.
Īsāghūjī
By Al-Abharī (1200–1265). The Arabic adaptation of Porphyry's Isagoge — the standard gateway into formal logic in the classical Islamic curriculum. Used in madrasas across the Islamic world for eight centuries.

What is Mantiq in Islam?
Mantiq is the Arabic term for logic — the science of correct reasoning. In the classical Islamic tradition, it was considered an essential tool for studying theology, Quran, and Fiqh, providing the framework for evaluating arguments and avoiding fallacies.
Why did classical Islamic scholars teach Mantiq?
Classical scholars taught Mantiq because reasoning correctly about Islamic sources requires a formal framework. Al-Ghazali identified thirty valid syllogistic forms in the Quran. Allah commands "afalā ta'qilūn" forty-nine times. Mantiq is the science built to answer that command.
What grade level is the Mantiq curriculum for?
The FISLI Mantiq curriculum is designed for high school students as the culminating fifth discipline of the FISLI sequence. Prerequisites: completion of the Sirah, Aqidah, Ulum al-Quran, and Hadith sequences.
What classical texts does FISLI Mantiq use?
Al-Sullam al-Munawraq by Al-Akhdarī and the Isaghuji as interpreted by Al-Abharī — the standard introductory logic texts used in classical Islamic seminaries for centuries.
