Аннотация:Nasir-i Khusraw was one of the first Persian poets of Classic period who used poetic form of qasida for propagation of religious doctrine. In his works the traditional panegyric qasida, one of the most popular genres of court poetry, changed its content to sermon and preaching. The poet preserved the polythematic nature of qasida but combined devices of poetry and sermon (rhetoric questions, repetition of the same maxims in different word form, illustrative examples and so on).
