The Great Interpretation or Keys of the Unseen 16/1

He is the greatest interpreter by opinion and reason, and in it, the author mentions the occasion of the surah with others, and mentions the occasions between the verses, and he digresses into cosmic sciences, and expands on them, as well as mentioning issues of fundamentals, grammar, rhetoric, and rational deductions. Al-Razi clarifies in his interpretation the meanings of the Noble Quran, its signals, and includes lengthy research in various sciences, such as theology, the sayings of philosophers and wise men. He mentions the doctrines of the jurists and their evidence in the verses of rulings, and he advocates for the Ash'ari school of belief, and responds to the Mu'tazila, and the sayings of the misguided groups, and refutes their doctrines, as well as responding to philosophers. However, Al-Razi did not complete it, so Shihab al-Din al-Khobi al-Dimashqi (639 AH) came and completed part of it, then Nizam al-Din al-Qumuli (727 AH) came after him and finished it to the end, without distinguishing the original from the supplement. Egyptian edition, with hadiths arranged, in 16 volumes.
