The book "Islah al-Khalal al-Waqi' fi al-Jumal li al-Zajjaji" (Correcting the Defect in al-Zajjaji's 'al-Jumal') is an important work presented in an engaging and accessible style. In it, the author addresses the renowned book "al-Jumal" by al-Zajjaji, not with the aim of supplementing it, but to correct its flaws and errors. He supports his views with rational and textual evidence, drawing upon the opinions of numerous early grammarians.
