«فَحُرُوفُ «فِي الْقِصَاصِ حَيَاةٌ» مَعَ التَّنْوِينِ أَحَدَ عَشَرَ»
The letters of “fī l-qiṣāṣi ḥayāh,” including tanwīn, are eleven.
The passage contrasts the Qur’anic expression and the familiar maxim both in length and semantic quality. The count concerns pronounced letters, with an explicit discussion of how tanwīn is counted; it should not be confused with modern typographic characters or unrelated spelling conventions.
The conclusion is broader than arithmetic: the Qur’anic phrase uses economical wording to convey a more precise and expansive meaning.
