The anonymous Persian poet, Seif-e-Esfarangi was probably born in the 6^th century (lunar year). His hometown according to the biographers' dictum, was Sfarang, one of the environs of Samarqand. With regard to this point, his poetry-book (divān) enjoys a special importance for the evaluation of the language of Māwarā-e-Nahr, just like those of Am'aq-e-Bokhāri, Mawlavi-e-Balkhi and Suzani-e- Samarqandi. Although it is needless to say that Seif is not leading in poetry. Seif has considered lots of his contemporaries and predecessors and has patterned their odes; Among these, one can note to Mas'ud-e- Sa'd, Amir Moe'zi, osmān-e- mokhtāri, Am'aq-e-Bokhāri, Sanāyi, Anvari, mojir and khāqāni, but the influence of khāqāni on Seif is more striking.

In this article, attempts are made to show some of the verbal and semantic similarities between the lines of Seif and khāqāni. These similarities could provide clues to the point that  Seif has viewed khāqān'is poetry-book.
