Al-Asmaʿi (, ʿAbd al-Malik ibn Qurayb al-Aṣmaʿī ; -828/833 CE), or Asmai; an early philologist and one of three leading Arabic grammarians of the Basra school. Celebrated at the court of the Abbasid caliph, Hārūn al-Rashīd, as polymath and prolific author on philology, poetry, genealogy, and natural science, he pioneered zoology studies in animal-human anatomical science. He compiled an important poetry anthology, the Asma'iyyat, and was credited with composing an epic on the life of Antarah ibn Shaddad. A protégé of Al-Khalil ibn Ahmad al-Farahidi and Abu 'Amr ibn al-'Ala', he was a contemporary and rival of Abū ʿUbaidah and Sibawayhi also of the Basran school. Ibn Isḥaq al-Nadīm's c.10th biography of al-Aṣma’ī follows the “isnad” narrative or ‘chain-of-transmission’ tradition. Al-Nadīm reports Abū ‘Abd Allāh ibn Muqlah's written report of Tha’lab's report, giving Al-Aṣma’ī‘s full name as ’’‘Abd al-Malik ibn Qurayb ibn ‘Abd al-Malik ibn ‘Ali ibn Aṣma’ī ibn Muẓahhir ibn ‘Amr ibn ‘Abd Allah al-Bāhilī.’’’ The celebrated c.13th biographer Ibn Khallikān calls al-Aṣmaʿī “a complete master of the Arabic language,” and “the most eminent of all transmitters of the oral history and rare expressions of the language.”. His account includes collected anecdotes of numerous adventures. Biography His father was Qurayb Abū Bakr from ‘Āṣim and his son was Sa’īd. He belonged to the family of the celebrated poet Abū ‘Uyaynah al-Muhallabī. Al-Aṣma’ī was descended from Adnān and the tribe of Bahila. The governor of Basra brought him to the notice of the caliph, Harun al-Rashid, who made him tutor to his sons, Al-Amin and Al-Ma'mun. It was said Al-Rashid was an insomniac, and that he once held an all-night discussion with al-Asmaʿi on pre-Islamic and early Arabic poetry. Al-Aṣma’ī was popular with the influential Barmakid viziers and acquired wealth as a property owner in Basra. Some of his protégés attained high rank as literary men. Among his students was the noted musician Ishaq al-Mawsili. His ambitious aim to catalogue the complete Arabic language in its purest form, led to a period he spent roaming with desert Bedouin tribes, observing and recording their speech patterns. Rivalry between Al-Aṣma’ī and Abū ‘Ubaida His great critic Abū ʿUbaida was a member of the Shu'ubiyya movement, a chiefly Persian cultural movement. Al-Aṣma’ī, as an Arab nationalist and champion of the Arabic language, rejected foreign linguistic and literary influences. Al-Nadīm cites a report of Abū ‘Ubaida that al-Aṣma’ī claimed his father travelled on a
