This study highlights Al-Radhi's attitudes in his book "Sharh AL-Kafia" towards AL-Akhfash ALAwsat' opinions. It illustrates ninety-four issues in which AL-Radhi disagreed with AL-Akhfash in seventy of them while they both agreed only in twenty- four. My approach (methodology) in this study can be summarized in the following points: - A title for each issue showing either agreement or disagreement between the two linguists is given. - ALRadhi's text, which includes AL-Akhfash opinion, is included at the top of each issue. - Eliciting Al-Akhfash's prospective and then presenting AIRadhi's attitude. -The researchers' point of view is mentioned at the end of each issue. - Each issue is placed in accordance with its sequence in "Sharh AL-Kafia. This study came out with the following conclusions: In their syntactic style, both AL-Radhi and AL-Akhfash depended on the standard syntactic principles such as listening, consensus* and reasoning with a balanced use of them by AL-Radhi while a slight derivation is observed by AL-Akhfash in this regard. * AL-Radhi was a precise linguist who did not accept opinions in various issues before he examined them thoroughly and reflects them to his linguistic prospective and followed a scientific approach in that. *Both AL-Radhi and AL-Akhfash have valuable points of view that can be of great value to linguistic studies. On the other hand, they have some views that were not within the linguistic context as indicated through the study. *AL-Radhi suffered inaccuracy when attributing opinions to AL-Akhfash as he attributed some opinions to AL-Akhfash who did not really expressed them or ignored some other opinions that AL-Akhfash adopted.
