Qur’anic verse endings frequently exhibit sonic harmony. Rhetorical analysis may compare these with sajʿ, while fawāṣil al-āyāt remains an appropriate separate term for Qur’anic endings.
«وَالنَّجْمِ إِذَا هَوَىٰ مَا ضَلَّ صَاحِبُكُمْ وَمَا غَوَىٰ»
“By the star when it sets: your companion has neither strayed nor erred.”
Hawā and ghawā provide a clear cadence. Yet the central effect is the movement from oath to affirmation, not a sound pattern imposed on the meaning.
