Al-Insaf fi Masail al-Khilaf Bayn al-Nahwiyyin - Ibn al-Anbari

Kamal al-Din al-Anbari's book "Al-Insaf fi Masail al-Khilaf Bayn al-Nahwiyyin al-Basriyyin wa al-Kufiyyin" (Equity in Matters of Disagreement Between the Basran and Kufan Grammarians) is a unique reference in its treatment of the grammatical differences between the schools of Al-Basra and Al-Kufa. Al-Anbari did not merely present these differences; he systematically analyzed them, clarifying the points of disagreement and agreement between the two schools, and using evidence and proofs to favor the most likely opinions.

In his book, al-Anbari focused on one hundred and twenty controversial issues, covering a wide range of Arabic grammar topics, such as inflection and syntax, derivation, and morphology. His presentation style is characterized by presenting the views of both the Basrans and Kufans in a balanced manner, mentioning the evidence and examples of each group, then moving on to a detailed analysis of these views, choosing the most likely one based on the strength of the evidence.

"Al-Insaf fi Masail al-Khilaf" is considered a valuable source for anyone interested in the Arabic language and its sciences, as it provides a clear vision of the grammatical differences between the Basran and Kufan schools and contributes to understanding the principles of each school and its approach to dealing with the language. The book is also distinguished by its precise scientific method in research and discussion, as it relies on evidence and proofs and avoids bias and prejudice.
