The explanation of Al-Kafia by Ibn al-Hajib is a concise yet respected book in grammar. It gained notable fame among scholars, who eagerly explained it, annotating and commenting on it. One of the most important commentaries is by Al-Radi Al-Istarabadi, who detailed Ibn al-Hajib's words, offering thorough explanations and commentary, using evidence from Quranic verses, Hadiths, poetic examples, and the sayings of Ali ibn Abi Talib in Nahj al-Balaghah. He presented various scholarly opinions on a single grammatical issue, providing his input without any bias or rigidity. We have included useful annotations in this edition and compiled a separate volume for the book's general scientific indexes. Author: Al-Radi Al-Istarabadi. Editor: Emil Badii Jacob.
