Abu ʾl-Rūḥ ʿĪsā ibn ʿAlī ibn Ḥassān al-Asadī (died 1262) was a Muslim writer. Ibn Manglī describes him as an expert on hunting who lived in the 6th century since the Hijra (1100s) under the Ayyubid dynasty. Between 1237 and 1242, after 23 years of traveling throughout the Islamic world, he wrote an encyclopaedia on falconry, . It contains 578 chapters on hunting birds and other animals (hunting dogs, cheetahs) used in falconry; the history of falconry, including celebrated anecdotes; the health, training and veterinary care of birds; the legal and religious position of falconry in the Islamic world; and falconers' sayings and poems. It was the most comprehensive work on hunting in Arabic for its time.
There are five surviving manuscripts of the known. Manuscript 3814 in the Hagia Sophia dates to 1273. There is no printed edition of the text, although three chapters on the use of the raven ("Corvus ruficollis") have been translated into French by François Viré from the manuscript Árabe 903 in El Escorial, which dates to 1589. The Escorial manuscript contains 302 folios. Select chapters of the have also been translated into English directly from manuscript. The was used as a base text by Ibn Manglī for his own hunting treatise, , completed in 1371–1372. Ibn Manglī criticizes al-Asadī for his scepticism. After describing how vultures soak themselves in lakes, cover themselvse in sand and then shake the sand off themselves into the eyes of wild asses in order to trap them, Ibn Manglī notes that al-Asadī rejects such stories.
