The Quran as a Legal Source: Linguistic Analysis

The Quran's status as the primary source of Islamic law is universally affirmed by Muslim scholars, but the mechanism by which Quranic text generates legal rulings is a matter of considerable theoretical complexity. Since the Quran is an Arabic text, its legal implications are mediated through Arabic linguistic categories, and al-Razi's treatment in the Mahsul devotes extensive attention to the linguistic analysis necessary for proper legal derivation. The Arabic language as a system of meaning is not univocal: a single word may carry multiple established meanings (musharak), an expression may be used literally or metaphorically (haqiqa vs. majaz), a text may address a universal class or a specific instance ('amm vs. khass), and a ruling stated in absolute terms may be conditioned by other textual evidence (mutlaq vs. muqayyad). Each of these distinctions directly affects how legal rulings are derived from Quranic statements.

The general-particular (amm-khass) distinction is perhaps the most practically significant in legal derivation. When the Quran uses a general term, does it bind all instances that fall under the term's scope, or only those that were specifically intended by the context of revelation? Al-Razi examines the classic Shafi'i position that a general expression (lafz 'amm) retains its universality unless specific evidence for restriction is found, contrasted with the Hanafi position that general expressions in the Quran convey only probability (dhann) of universal application and may be restricted by solitary hadith reports. This seemingly technical disagreement has enormous practical consequences: if a Quranic ruling is general and a solitary hadith appears to restrict it, the Shafi'i and Hanafi jurists will reach different conclusions about whether the restriction is valid, generating differing legal outcomes across many questions.

Al-Razi's treatment of the literal-metaphorical (haqiqa-majaz) distinction reflects his background in Arabic rhetoric and his engagement with the Islamic philosophical tradition. He acknowledges that the Quran employs metaphorical language extensively, as befits a text of supreme literary quality, but argues that the default interpretation of any legal text must be literal unless contextual evidence compels a metaphorical reading. The reasons for this default are both practical and theoretical: practical, because if metaphorical readings were freely permitted without constraint, jurists could justify almost any ruling by appeal to some metaphorical interpretation; theoretical, because the communicative function of legal texts is to convey determinate obligations, and metaphorical readings introduce indeterminacy that undermines this function. Al-Razi engages the positions of the Arabic linguists and rhetoricians carefully, showing how legal and literary readings of the Quran, while related, serve different purposes.

The distinction between absolute (mutlaq) and qualified (muqayyad) expressions generates one of the most intricate debates in Quranic legal interpretation. When the Quran in one verse uses an absolute expression (for example, 'a slave' without qualification) and in another verse qualifies the same term (for example, 'a believing slave'), should the absolute expression in the first verse be read as implicitly qualified by the second? Al-Razi analyzes the conditions under which such 'carriage' (haml) of the qualified onto the absolute is justified. His framework distinguishes cases where both verses address the same ruling and the same cause from cases where they address different rulings or different causes, and establishes that carriage is appropriate in the former case but not necessarily in the latter. This fine-grained analysis exemplifies the Mahsul's combination of logical rigor and practical legal orientation.
