The evaluation of the Historic- Scientific Character of Ibn- Wahshiyya Based on the study of Al- Filaha- al- Nabatiyya

'' Al- Filaha- al- Nabatiyya'' is an important agricultural book of the Islamic Civilization as well as the greatest work written by Ibn- wahshiyya of kaldan (246LH 865 AD).Ibn- wahshiyya Claims that the work is a translation of the ancient writings in Babel, while there are some disputes among many occidentalists and researchers in this concern. Some have considered that not only the work could not be attributed to him, but he is also a false character made by Ibn- Zayyat, who claimed to be a pupil of his, and thus, the narrator of the book.It is noteworthy to say that the book contains a lot of superstitions, tales, and myths as well as some applied scientific matters in botany and in Agronomy.During the 19th century, some occidentalists suggested that Ibn- wahshiyya's claim to attribute the book to kaldanians is false and not true.
