This lesson began with the definition of the Book of Allah: the Qur’an revealed to the Messenger ﷺ, preserved in written codices, and transmitted through tawatur. The first of four general classifications then considered words with regard to their assigned meaning.
Its four categories are khass, ‘amm, mushtarak and mu’awwal. Khass signifies its determinate assigned meaning; Zayd, rajul, insan and thalathah illustrate different kinds of such signification.
The next lesson studies ‘amm, general expressions and how their scope differs from that of khass.
