ÿAbd al-RaḥmÃÂn ibn Naá¹£r ibn ÿAbdallÃÂh (died 1193), called al-Shayzarë or al-NabarÃÂwë, was a Syrian Arabic author on various topics. He wrote a work on the proper behaviour of a ruler for Saladin, a work on various drugs and other remedies for sexual and erotic needs, a work on the interpretation of dreams and a manual for the muḥtasib (market supervisor).
The full name of al-Shayzarë is uncertain. His given name and patronymic, ÿAbd al-RaḥmÃÂn ibn Naá¹£r ibn ÿAbdallÃÂh, appear consistently the same, but his laqab (cognomen) and nisba (surname) vary in the manuscripts. His laqab appears as Taqë al-Dën, Zayn al-Dën or JamÃÂl al-Dën, while his nisba may be al-NibrÃÂwë, al-Ṭabrëzë, al-ÿAdawë, al-ShërÃÂzë or al-Shayzarë. Carl Brockelmann gives his full name as JalÃÂl al-Dën Abu þl-Najëb Abi þl-Faá¸ÂÃÂþil ÿAbd al-RaḥmÃÂn ibn Naá¹£r AllÃÂh ibn ÿAbdallÃÂh ibn Naá¹£r ibn ÿAbdallÃÂh al-Shayzarë al-Ṭabrëzë al-ÿAdawë al-NabarÃÂwë. Given the prominence of Shayzar in his work, al-Shayzarë is his most likely nisba.
Little is known of al-Shayzarë's life, since he does not appear in the classical biographical dictionaries. He was a contemporary of Saladin (). According to Ibn QÃÂdë ShahbÃÂ's al-KawÃÂkib al-durrëya fiþ l-sërat al-Nà «rëya, written some three centuries later, al-Shayzarë was a native of Syria. This is consistent with the internal evidence of his writings, which indicates at least that he spent much time in Syria. Later sources are even more specific. According to ḤÃÂjjë Khalëfa, he was a judge in Tiberias; per Ferdinand Wüstenfeld, a physician in Aleppo. His writings do not reveal his occupation, although it has sometimes been assumed he was a muḥtasib.
Al-Shayzarë may have died in 1193, the same year as Saladin.
Five works in Arabic are attributed to al-Shayzarë.
