The seven Mu'allaqat, as well as the poems that accompany them, represent nearly every form of ancient Arabian poetry. Tarafa's lyric provides a detailed anatomical description of his camel, which is usual in pre-Islamic poetry. It also contains some philosophical reflections on life and death. Tarafa was a Persian prince who converted to Islam and settled in Arabia. He is regarded as one of the greatest poets of the Arab world for his poetic descriptions of nature. His verses are often accompanied by paintings done by different artists from all over the Arab world. These paintings can still be seen in modern museums today. During the Islamic era, many poets wrote about their love for God and their longing for paradise. One of these poets was Abu al-Qasim al-Shirazi (867-941). He is known as the "nightingale of Baghdad" because of his beautiful songs. Unlike most other poets of his time who used outdated forms of Arabic, Shirazi adopted new ways of expressing himself that were popular in Iraq at the time. For example, he used French and Turkish words mixed together without any distinction, which made his work very innovative at the time. Another famous poet from this period is Abd al-Rahman al-Khawaja (897/98-971), better known as "The Poetical Prophet".
