Is the book "Al-Hawi fi Tafsir" by Sheikh Abdul Rahman bin Muhammad Al-Qamash considered a Bid'i (innovative) and a waste of time, especially with the deviations in the نقلت فيه "introduction of العلامة الألوسي," or does it contain intended linguistic subtleties and benefits?

It is not possible to judge the book as an absolute innovation or commendation without a thorough review. However, its author mentioned that he compiled it from theades of tafsir (definition) (exegesis) and incorporated the research of verified scholars. The book has been described as a massive encyclopedia on the exegesis of the Quran and its sciences, containing diverse scholarly research. It is possible that the author quoted from Al-Alusi's tafsir and other books of exegesis.
