RT Article T1 The Phonetics and Phonology of Single-Letter Prefixed Chapters in the Holy Quran: a Case Study of Chapters Saad, Qaaf, and Nun JF Al-Bayān VO 23 IS 3 SP 547 OP 577 A1 Mohammed Nour Abu-Guba A1 Sumaya Daoud A1 Abdallah Abu Qub’a A2 Sumaya Daoud A2 Abdallah Abu Qub’a LA English YR 2025 UL https://ixtheo.de/Record/1960901621 AB The Holy Quran contains 29 chapters (Suras) that start with disjointed letters, a phenomenon that has long been a matter of debate in Quranic exegesis. To contribute to understanding the mysterious nature of these letters, this paper examines them from a phonological and phonetic perspective. Specifically, the study compares three chapters that start with a single disjointed letter in the Holy Quran. The three chapters were analyzed at the phonemic, syllabic, and prosodic word levels. Results show that these three chapters share many features, which align with the fact that they begin with a single disjointed letter. Moreover, the two chapters that start with similar consonants, namely Sad and Qaaf, which start with an obstruent, are more similar to each other than to Chapter Nun, which begins with the sonorant /n/. These results reveal that the three letters could not have been chosen arbitrarily. This constitutes a strong case against many revisionist theories. Future research should extend the analysis to other Quranic chapters, both with and without disjointed letters, to corroborate the findings of this study.
