Variations among Qur’anic readings pose a continuing linguistic question because authenticated recitations may realize different Arabic morphological and syntactic patterns while transmitting a coherent scriptural discourse. This study examines how ?Abduh al-R?jih? explains such variation in al-Lahj?t al-?Arabiyyah f? al-Qir???t al-Qur??niyyah. It employs a qualitative library and document-study design. The unit of analysis is each qir???t example that al-R?jih? associates with Arabic morphology or syntax; the primary corpus is his discussion of these two levels, read comparatively with the Qur’anic passages and supporting works already cited in the manuscript. Relevant passages were identified, documented, grouped by linguistic category, compared across reported readings, and interpreted in relation to the grammatical explanation supplied by the sources. The analysis shows that morphological variation concerns pronouns, nominal forms, verbal patterns, intensive forms, tense or aspect, substitution, and omission or retention. Syntactic variation concerns grammatical gender, the government of m?, the separator pronoun, dual marking, verb–subject agreement, exception and substitution, case assignment, and word order. These variants generally represent grammatically licensed alternatives; some alter form or emphasis without changing the central proposition, whereas others invite different syntactic analyses. The study concludes that al-R?jih?’s framework connects qir???t evidence with historically attested Arabic usage and offers a structured basis for teaching morphology and syntax through Qur’anic examples. Its conclusions remain limited to the selected corpus and do not cover phonetic or semantic variation.
