In the Department of Arabic Language, College of Arts, Basrah University, a master's thesis was discussed entitled  "A Book of Letters in Language by Ibn Al-Sayed Al-Battlbussi: A Linguistic Arguing Study".

 The thesis presented by the student Omar Jabbar Nehme Mudhi included three chapters. The first chapter dealt with the arguing connections. The second chapter dealt with the arguing factors, while the third chapter dealt with the function levels and the arguing positions.

 The research discussed the study of the linguistic arguing phenomenon in the book Risalah fi al-Linguistics by Ibn al-Sayed al-Battalbussi, as the researcher worked to uncover the links, factors, function levels, and arguing positions in which the texts of Al-Battlbussi abounded, and how these arguing mechanisms gained the texts of the letters a high arguing capacity in persuasion.

The study showed one type of the arguing function levels, namely the ascending function levels, and refuted the existence of cumulative function levels or descending ones in the arguing theory. And Al-Battlbussi arranged his arguments according to a hierarchical hierarchy based on the differentiation between arguments and disparity in strength and weakness, starting with the weaker argument at the base of the arguing scale and starting with the argument in the most knowledgeable of the arguing function levels.
