The Historical Development of Maqasid Theory

The theoretical foundations of maqasid thinking were laid well before Ibn Ashur's systematic treatment of the subject. The earliest significant articulations appear in the work of Imam al-Haramayn al-Juwayni (d. 478 AH), who identified three levels of legal objectives: necessities (daruriyyat), which the law protects because their absence would cause the collapse of social order; needs (hajiyyat), whose neglect causes hardship without reaching the level of catastrophe; and improvements (tahsiniyyat), which refine and beautify human life within the framework already established. This three-tier structure became the standard scaffolding for all subsequent maqasid theory.

Al-Ghazali (d. 505 AH), al-Juwayni's most brilliant student, developed this framework further in his landmark work al-Mustasfa. He specified the five fundamental necessities that Islamic law protects: religion (din), life (nafs), intellect (aql), lineage (nasl), and property (mal). These five became canonical in the usul al-fiqh tradition and are cited in every subsequent treatment of maqasid. Al-Ghazali also developed the concept of maslaha mursalah, unrestricted public interest, as a legal source grounded in these objectives. His treatment, while influential, was cautious: he accepted maslaha as legally operative only when it aligned with the established purposes of the law and did not contradict any clear text.

Al-'Izz ibn Abd al-Salam (d. 660 AH) extended maqasid thinking in a more practical direction, arguing in his Qawa'id al-Ahkam that the entire Shariah could be summarized as the securing of benefits and the prevention of harms. Ibn al-Qayyim al-Jawziyyah (d. 751 AH) pursued this idea vigorously, insisting that any ruling inconsistent with justice, mercy, wisdom, and benefit could not in truth be a ruling of the Shariah regardless of its formal legal pedigree. His work opened a bold avenue in Islamic legal thought that subsequent generations found both inspiring and, in the hands of the incautious, potentially destabilizing.

Abu Ishaq al-Shatibi (d. 790 AH) stands as the most systematic pre-modern theorist of the maqasid, and his al-Muwafaqat is the immediate predecessor to Ibn Ashur's work. Al-Shatibi argued that the maqasid provided the ultimate basis for all legal reasoning, that individual rulings derive their authority from the objectives they serve, and that the jurist who lost sight of the objectives while focusing only on the letter of the rules had fundamentally misunderstood Islamic law. Ibn Ashur's contribution, building on this rich tradition, was to bring greater conceptual precision, to challenge certain inherited assumptions about the five daruriyyat, and to bring maqasid theory into direct engagement with the modern world's unprecedented legal and social questions.
