Abu Layla is one of the old linguists who contributed greatly in linguistics. Some of his narrations were found in some references especially in dictionaries such (AlAyn) which was written by ALKhalil Ibn Ahmad AL Fraheedi (died 175 A.H ). The present research is of an introduction and two parts. Part one includes an autobiography of Abu Layla as well as a study of his narrations in (AlAyn). Part two includes the texts which are classified alphabetically. I have mentioned the refrences in the footnotes.
