SUMMARY
This research paper examines the rhythmic composition of a long poem written by the Abbasids poet (Abi_ Ya,qub Al- Khuraymi) in which he laments over the city of Baghdad after the destruction and devastation that have befallen it, as a result of the conflict between al-Ameen and al- Mamoun, the sons of the Abbasid Caliph Haroun al-Rashid. The poet was keen to exploit the components of the rhythm internally and externally to construct the poem to build psychological reactions. To attain this goal, the poem has its own internal and external rhythm, parallelism, poetic inlay rhyme, and narrative style.
