Abrogation, Conflict of Evidence, and Prioritization

The Islamic legal tradition acknowledges that divine legislation was revealed progressively over the twenty-three years of the Prophetic mission, and that some earlier rulings were superseded by later ones through a process known as naskh (abrogation). Al-Razi's treatment of abrogation in the Mahsul is among the most analytically careful in the classical usul literature. He defines abrogation precisely as the termination of a ruling by a subsequent divine communication in a manner that would, absent the later communication, have been understood as permanent. This definition distinguishes genuine abrogation from clarification (bayan), which resolves an apparent ruling by showing it was always conditional, and from specification (takhsis), which restricts a general ruling without ending it. These distinctions matter enormously in practice: a jurist who misidentifies a clarification as an abrogation, or vice versa, will derive fundamentally wrong legal conclusions from the texts.

Al-Razi categorizes abrogation across several dimensions. The Quran may abrogate the Quran; the Sunnah may abrogate the Sunnah; and the scholarly debate concerns whether the Quran can be abrogated by the Sunnah or the Sunnah by the Quran. Al-Razi follows the mainstream Shafi'i position that the Quran and Sunnah are co-equal revelations in terms of their divine authority, even though they differ in mode of transmission, and that in principle either may abrogate the other when the evidence for abrogation is sufficiently clear. He also examines the case of abrogation of recitation while preserving the ruling, and abrogation of the ruling while preserving the recitation, both of which are established in classical Sunni scholarship with reference to specific examples from the Quranic text and hadith literature.

When two pieces of evidence appear to conflict without one abrogating the other, al-Razi presents a hierarchical methodology for resolution. The first step is to attempt reconciliation (jam'): perhaps the apparent conflict dissolves under more careful reading, with one text addressing a different situation from the other, or one being more specific than the other in a way that allows both to be operative. If reconciliation fails, the second step is to determine priority (tarjih): which of the two conflicting evidences is stronger, based on criteria such as the certainty of its transmission, the clarity of its linguistic expression, and the strength of supporting evidence from other sources? If prioritization is indeterminate, the third step is to suspend judgment (tawaqquf) and refuse to derive a ruling on the question. This three-step methodology provides a principled framework for handling the inevitable tensions that arise when a large body of texts from different times and contexts is applied to legal questions.

Al-Razi's treatment of tarjih (prioritization) is particularly detailed, listing dozens of criteria by which competing evidences may be ranked. On the side of transmission, an evidence is stronger if it is mutawatir rather than solitary, if its narrators have higher reliability ratings, or if it is reported by a narrator who has firsthand knowledge of the relevant legal domain. On the side of textual expression, an evidence is stronger if its relevant term is used in its primary literal meaning rather than metaphorically, if it is expressed in direct speech rather than implication, or if its ruling is presented as absolute rather than qualified. These ranking criteria reflect the Mahsul's commitment to providing the working jurist with systematic tools rather than leaving legal derivation to intuition or unguided case-by-case judgment.
