hagiography are more considerable in these two centuries; so that there are about sixty of such works written in a period of two hundred years. Discovering the reason behind such a growth is possible through the study of the remaining hagiographic books and the historical reports. The present research is an attempt to this end. The book of Naqd written by 'Abd al-Jalil Qazvini is one of the most important works having dealt with the issue of hagiographic sermons. It has illustrated the blurred conditions of that age properly. This book is a good source for the identification of the reasons and causes of the increase of hagiographies in these centuries. It seems that there were various political, scientific and culture reasons behind the growth in such a style of writing. Some of these reasons are referred to in this article.
