Stylistics of a work to recognize the individual and distinct style of a writer or poet is called personal/individual stylistics. This kind of stylistics is very important, but unfortunately, in Iran has been less scientifically addressed. One of the stylistic approaches stemming from structural linguistics is a layer stylistics which analyzes different layers such as phonetic, lexical, syntactic, rhetorical and ideological ones in an artwork. This type of stylistics can be considered the most complete and accurate method of this science. In this research, the poems of Kamal-al-Din Ismail and Athir Umani (6-7 Hijri century) have been surveyed in layer stylistics. Because of all layers of their poems do not fit in this article, only phonetic layer of poems has been analyzed and style of two poets in this layer has been compared. This study demonstrates that these two poets in this layer have a special style, and they have attended particularly to smooth weights, row processing, using a variety of verbal innovative and sometimes special rhyme array.
