Ibn al-Muqaffa'’s known works including Kalila wa Dimna are listed in al-Fihrist and he is described by al-Nadim as Min aI-Summar (a night-discourser). Khulusi suggests that in the same way that Ibn al-Muqaffa' translated Kalila wa Dimna into Arabic, he had the scholastic ability to translate the original fables from Hazaar Afsaanah and to develop these in Arabic and as was customary at that time to verbally relay some of the stories. Different recollections of the tales by various scribes and copyists and later alterations could account for the different versions of the stories and the obscurity of their author.
