Saj'
Saj‘,( Arabic: سـجـع) is a form of rhymed prose in Arabic literature. It is named so because of its evenness or monotony, or from a fancied resemblance between its rhythm and the cooing of a dove. It is a highly artificial style of prose, characterized by a kind of rhythm as well as rhyme. Saj is used in sacred literature, including parts of the Quran, and in secular literature, such as the One Thousand and One Nights.
