Al-Qifti' means(d. 646 AH / 1248 AD) in his evaluation of the writings of the Moroccans and Andalusians contained in his book 'Inbah Al-Ruwat ala Anban al-Nuhat'

The research dealt with the oriental viewpoint in Moroccan and Andalusian literature on linguistics and grammar through an oriental historian Al-Qafti and his book Inbah al-Ruwat, in which he often shed light on their writings and evaluated a large number of them and showed his point of view about them, whether positive or negative, and it is important to show that Al-Qifti had several means or criteria in evaluating these books, including his own evaluation of the book after reviewing it, or by relying on the opinions of scholars of his time. we find that he asks a certain scholar about a book to know his opinion about it, and sometimes we fine a similar evaluation between him and other scholars. Or he reads the book and then evaluates it with his own evaluation and then presents it to other scholars of his time to see his point of view about it to reach an accurate evaluation of the book. He also relied on Evaluation of previous sources in his evaluation of a number of Moroccan and Andalusian books which he did not read, and the most prominent of those sources are the book of Tabaqat AL-nahaween wa AL-logaween by mohammed ibn hasan al-zubaidi and the book oh AL-silaa by ibn bashkwal. After comparison, we found texts which indicated that Al-Qifti relied in his evaluation of a number Moroccan and Andalusian books on these two books.
