The author explains that jahr, shiddah, istiʿlāʾ and iṭbāq are strong qualities, and that the combination of qualities affects how a letter is ranked. The section gives five grades:
Qawī: ج د ص غ ر ب; Aqwā: ط ض ظ ق; Mutawassiṭ: ء ا ز ت خ ذ ع ك; Ḍaʿīf: س ش ل و ي; Aḍʿaf: ث ح ن م ف ه.
These are the book's phonetic classifications, not a ranking of religious value or importance. “Weak” must never mean inaudible or omitted. Every letter must still be pronounced correctly.
