Was the Quran Written by the Prophet? -A Stylometric Investigation Using the Interrogative Form

Abstract

In this investigation, we try to see whether the holy Quran could have been written or dictated by the Prophet (Pbuh), thanks to a stylometric discriminative analysis of the corresponding Author styles. The originality of this research work lies in the use of a new set of linguistic features based on 26 interrogative features and a special fusion, which we called logarithmic feature fusion or LFF. The experiments have shown that the proposed features, with their fusion, are interesting. Furthermore, the application of discrimination on the Quran and Hadith has shown a great difference in Author style between the two books, which confirms that the Quran could not be written or dictated by the Prophet.
