الملخص حظي أبو حيان الأندلسي باهتمام ابن هشام .. فکان شارحاً لبعض مؤلفاته ،وذاکراً لمعظم آرائه في مصنفاته، وناقداً له يبّين مواضع الزلل في أقواله ويصوّبها، ويکشف عن مواطن النقص في مقدماته ويکملها، وقد عُرف بصرامة نقده ومخالفته لأستاذ النحو في زمانه، وشدة انحرافه عنه حتى ظن فيه بعض المتأخرين وبعض المحدثين ما قد يبعده عن حدود الموضوعية و الإنصاف في تناول آراء المخالفين له و الحکم لها أو عليها، ومن أجل الوقوف على حقيقة تلک المخالفة وذلک الانحراف تناول البحث نقد ابن هشام لأبي حيان في شرح اللمحة البدرية في نقاط محددة وهي: الحياة العلمية لأبي حيان الأندلسي وابن هشام الأنصاري ، ومظاهر مخالفة ابن هشام لأبي حيان ونقده لآرائه وحدوده في اللمحة البدرية، وأسباب انحرافه عنه وتجليات الموضوعية في نقد ابن هشام . Summary Abu Hayyan Al-Andalusi received the attention of Ibn Hisham .. He was an explanation of some of his books, mentioned most of his opinions in his compilations, and a critic of him showing the places of flaws in his statements and correcting them, revealing the deficiencies in his introductions and completing them, and he was known for his rigor and contradiction with the professor of grammar in his time, and the severity of his deviation from him. Even some of the later scholars and some modernists thought that it might move him away from the limits of objectivity and fairness in dealing with the opinions of those in conflict with him and judging them or on them, and in order to find out the truth of that violation and that deviation, the research dealt with Ibn Hisham's criticism of Abu Hayyan in explaining the Badriya insight into specific points, namely : The scientific life of Abu Hayyan Al-Andalusi and Ibn Hisham Al-Ansari, the manifestations of Ibn Hisham's contradiction to Abu Hayyan, his criticism of his views and his limits in the Badriya insight, the reasons for his deviation from him and the manifestations of objectivity in the criticism of Ibn Hisham.
