His author has not been tackled by an independent study that passes through his personality with all its intellectual and linguistic aspects although the author and his manuscript have mentioned in various books . This study falls into two parts; the first involves the biography of the author whereas the second is about his status, the men who had been influenced by him, his literary works whether verse or prose, and his death.
