This document discusses the linguistic qualities or attributes (sifaat) of Arabic letters. It defines sifaat al-huroof and explains how they help differentiate between letters produced from the same articulation point.
The document outlines three main categories of sifaat - permanent qualities that are always present, temporary qualities only present in some contexts, and lists some examples of each. It then analyzes each Arabic letter, describing the specific sifaat that apply such as whether a letter has hams (air expelled) or rakhawa (sound runs on). Examples are provided to illustrate applying the sifaat attributes to analyze letters.
