Hurûf-u müşebbehe in classical texts and muhaffef examples in the Qur'an

The study provides information on the meanings and uses of six-letter "hurûfu müşebbehe" letters, which resemble verbs. The uses of these letters are clarified through examples, including Qur'anic verses, prioritized poetry in the Arabic language, and colloquial expressions, making them undeniably reliable sources. Additionally, the consideration of eleven source works reaching back to the 4th century adds significant weight and importance to the topic. Our study consists of an introduction and two sections. The introduction provides information on the subject, importance, and purpose of the research. The first section processes information obtained from classical texts concârning hurûfu müşebbehe. As this information is processed based on chronology, when the same information appears in later works, comments and footnotes have been added only to specific topics. All information is sourced directly from the main texts, and works post-4th century have not been considered. In the second section, the occurrence of four specific lightweight particles in the Qur'an is discussed in four parts. Three verses likely containing these particles do not align with the reading of Âs, therefore they are not elaborated upon but are noted with comments and footnotes.
