More widely known than his poetry is his great anthology, the `Iqd al-Farid (The Unique Necklace), a work divided into 25 sections. The 13th section is named the middle jewel of the necklace, and the chapters on either side are named after other jewels. It is an adab book resembling Ibn Qutaybah's `Uyun al-akhbar (The Fountains of Story) and the writings of al-Jahiz from which it borrows largely. Although he spent all his life in al-Andalus and did not travel to the East like some other Andalusian scholars, most of the his book's material is drawn from the East Islamic world. Also, Ibn Abd Rabbih quoted no Andalusian compositions other than his own. He included in his book his 445-line Urjuza, a poem in the meter of the rajaz in which he narrate the warlike exploits of Abd al-Rahman al-Nasir, along with some of his eulogies of the Ummayads of al-Andalus.
