A master's thesis in the Department of Arabic Language at the College of Education, Qurna, University of Basra, discussed (The Morphological Reconciliation of Shafia Explainers in the Eighth Century Al-Hijwi) by researcher Hadeel Najm Abdullah

 Where the study dealt with six explanations of Ibn al-Hajib’s healer that appeared in the eighth century AH, which are the printed explanations, which are the most famous and most important among the other explanations that appeared in that century, which are:

 Explanation of Rukn al-Din al-Hasan al-Astarabadi (d. 715 AH).

  Explanation of Al-Khidr Al-Yazdi (d. 720 AH) Explanation of Al-Hassan bin Muhammad Al-Nisaburi, known as the system (d. 728 AH), Explanation of Mahmoud bin Muhammad Al-Arani Al-Sakanani (d. 734 AH), Explanation of Ahmed bin Al-Hassan Al-Jarbardi (d. 746 AH), and Explanation of Abdullah bin Muhammad Naqra Kar (d. 776 AH).

 The research included the explanations of the commentators on Ibn al-Hajib, and their corrections came in different forms, so sometimes the correction is in the structures and words, and sometimes it is in the rulings, and they have corrected a lot in the issues of disagreement, whether the disagreement is in the rulings, or in the buildings, they have corrected the doctrines that the compiler did not mention, and unlike that he did not Refer to him, and other forms of redress.

 In their revisions, the commentators relied on the sayings and opinions of scholars, headed by Sibawayh, as he is their first source in remediation, and they also inferred in some of their revisions what came from al-Mubarrad, al-Farra’, al-Zamakhshari, Ibn al-Qata’a and others, and also from the sources of their reconsideration of the Noble Qur’an and its readings, as well as the dialects of the Arabs, and at times they reconcile On the compiler, what they see and derive, so the source of their realization is their personal opinion.

 The rectification came with different words and expressions, including: (the compiler did not mention it), (he forgot about it), (he omitted it), (not correct), (it is not like that), (there is consideration), and others, and it may not be in any way. Of these phrases, but the reader knows it, and the research showed the wide knowledge of the commentators, and their mastery of language sciences and its grammar, so their corrections were in most of them good, and a few of them were weak, and some of them were okay.
