A qasida (also spelled qasidah) in Arabic "قصيدة", is a form of poetry from pre-Islamic Arabia. It typically runs more than 50 lines, and sometimes more than 100. It was later inherited by the Persians, where it became a rhymeless poem of more than 100 lines [1]. Properly, either all the lines rhyme [2], or every second line of the four-line verse rhymes [3].

The pre-Islamic qasida maintained a single elaborate meter throughout the poem, and every line rhymed. These poems are considered some of the most elaborate in the world.
