Distinctive Hanafi Maxims and the Majalla Legacy

Beyond the five universal maxims shared across all schools, Ibn Nujaym's Ashbah wan-Naza'ir documents a number of legal maxims that are particularly characteristic of Hanafi jurisprudence or that receive distinctive application within it. These maxims illuminate the methodology that makes the Hanafi school the largest and most geographically widespread of the four schools of Sunni Islamic law.

The maxim 'istihsan is evidence' (al-istihsan hujjah) is the most contested Hanafi contribution to legal theory. Imam Al-Shafi'i famously wrote 'whoever uses istihsan has made himself a lawgiver,' rejecting it as unprincipled departure from analogy. The Hanafi school responded by clarifying what istihsan means: not arbitrary preference, but the preference for a weaker analogy or textual position over a stronger one when the stronger would produce an unacceptable result that the Lawgiver clearly did not intend. Ibn Nujaym provides a nuanced account of this maxim and its legitimate applications, defending it against the Shafi'i critique.

The maxim 'custom among merchants is considered in commercial transactions' (al-'urf al-tijari mu'tabar) shows the Hanafi school's openness to commercial practice as a source of legal guidance in contractual matters. Ibn Nujaym documents cases where customary mercantile practice determines the default terms of a contract, the meaning of ambiguous language in an agreement, and the parties' obligations in unforeseen circumstances. This maxim made the Hanafi school particularly well-suited to govern the commercial life of the Ottoman Empire.

The maxim 'necessity permits the use of others' property without their consent to the extent required' underlies the Hanafi doctrines of compulsory sale (bay' al-idtirar) and the right of neighbors. Where someone's property is essential to prevent serious harm to another, the Hanafi school may require its sale at fair market value. Ibn Nujaym traces the limits of this principle carefully, ensuring it does not become a general permission to override property rights.

The Ottoman Majalla, promulgated between 1869 and 1876 as the first modern Islamic civil code, drew extensively on Ibn Nujaym's Ashbah wan-Naza'ir. The Majalla's opening ninety-nine articles — legal maxims stated as positive law — are derived almost directly from the classical maxims literature, with Ibn Nujaym as a primary source. This borrowing gave the maxims of the Ashbah a legal force and geographic reach they had never had as academic texts, extending from the Balkans to Arabia to North Africa.

The influence of Ibn Nujaym and the Ashbah wan-Naza'ir on contemporary Islamic law is substantial. Muslim-majority countries that retain elements of Islamic private law — particularly in family and inheritance matters — often rely on Hanafi doctrine as codified through the Majalla tradition. The maxims that Ibn Nujaym systematized continue to be applied by courts, scholars, and legal reformers seeking to adapt Islamic law to contemporary conditions.
