Invisible Repetitions in Linguistics refer to methods by which a morpheme or linguistic element is reflected implicitly and indirectly in a text, without the direct repetition of words, in order to enhance its coherence and impact. This technique strengthens the aesthetics and rhetoric of the text and conveys the message to the audience in an influential and subconscious manner. The aim of this research is to demonstrate how this literary device reinforces the mechanism and meaning of the Surah and makes its effect on the audience more meaningful. Using a descriptive-analytical approach, this article analyzes invisible repetitions in the Blessed Surah of Al-Layl. The findings of the research indicate that invisible repetitions create a coherent and pleasing structure. These repetitions, like invisible threads, connect various parts of the Surah, causing the verses to be perceived as a harmonious whole. They emphasize contrasts and dualities, such as the opposition between night and day or generosity and miserliness. Moreover, by creating rhythm and internal cadence, they enhance the eloquence of the Surah and elevate its meaning beyond ineffective speech. This technique subconsciously penetrates the audience's mind and effectively and consistently reinforces the central theme of the Surah.
