Ibn WÃÂá¹£il (AD 1208âÂÂ1298 ) was a Syrian judge, scholar and writer. He was a courtier and diplomat of the Ayyubids and their successors, the Mamlà «ks. Although trained as a religious scholar, in his own time he was renowned as a logician and today is most famous as a historian, especially of the Ayyubids. He also wrote works on poetry, medicine and astronomy.
Abà « ÿAbd AllÃÂh JamÃÂl al-Dën Muḥammad ibn SÃÂlim ibn Naá¹£r AllÃÂh ibn SÃÂlim ibn WÃÂá¹£il, commonly known simply as Ibn WÃÂá¹£il, was born in Ḥamàon 20 April 1208. His father was the qÃÂá¸Âë (judge) of Ḥamàand later al-Maÿarra, and worked as a mudarris (teacher) at the school known as the NÃÂá¹£iriyya by the Golden Gate in Jerusalem. He studied under his father. When the latter was away on the Ḥajj from 1227 to 1229, he took over some of his duties at the NÃÂá¹£iriyya. He witnessed the siege of Damascus in the spring of 1229. In 1230âÂÂ1231, he studied in Damascus and Aleppo, where he was taught by Ibn ShaddÃÂd. His main education was a religious one. He studied fiqh (jurisprudence) and ḥadëth (tradition), and issued opinions as a muftë.
In 1232, Ibn WÃÂá¹£il joined the court of al-NÃÂá¹£ir DÃÂÃ¾à «d, emir of Karak. There he studied under Shams al-Dën al-Khusrà «shÃÂhë. In 1234, he joined the court of al-MuáºÂaffar II, emir of ḤamÃÂ, who ordered him to help ÿAlam al-Dën Qayá¹£ar in constructing an astronomical observatory and an astrolabe. In 1236, he returned to Damascus, the ruled by the Emir ḤusÃÂm al-Dën ibn Abë ÿAlë, who became his patron.
In 1243âÂÂ1244, Ibn WÃÂá¹£il travelled with his relative Ibn Abi þl-Dam first to Baghdad and thence to Cairo. In Egypt, he studied under the physician Ibn al-Nafës. In 1252, he performed the Ḥajj in the company of ḤusÃÂm al-Dën ibn Abë ÿAlë. He returned to Cairo. In August 1261, he was sent by the Sultan Baybars on an embassy to King Manfred of Sicily. He met Manfred in Barletta. In 1264 or 1265, he moved back to ḤamÃÂ, where he was appointed chief qÃÂá¸Âë. He spent most of his time writing. He was blind in old age, dying aged 93 years according to the Islamic calendar.
Ibn WÃÂá¹£il wrote in Arabic. He wrote four works on logic, only two of which survive; four works of history; two works on poetry; and works on philosophical theology, astronomy and medicine, the last two being lost.
Ibn WÃÂá¹£il belonged to the "western" school of logic associated with Fakhr al-Dën al-RÃÂzë. In his work against logic, Ibn Taymiyya referred to Ibn WÃÂá¹£il as a "leading philosopher". His works on logic include two commentaries on the work of the Egyptian logician al-Khà «najë. The commentary on al-Khà «najë's al-Jumal fiþl-maná¹Âiq ('The Sum of Logic') was his most popular logical work and survives in four manuscript, including three bearing the dates AH 680 (AD 1281), 738 (1337âÂÂ1338) and 746 (1345). The other commentary on al-Khà «najë does not survive. Ibn WÃÂá¹£il also wrote a logical treatise, al-RisÃÂla al-anbrà «riyya ('The Imperial Treatise'), for King Manfred of Sicily. This survives in a single manuscript from 1281 under the title Nukhbat al-fikar fë tathqëf al-naáºÂar. Ibn WÃÂá¹£il later revised this treatise under the title Nukhbat al-fikar fiþl-maná¹Âiq ('The Pick of Reflection on Logic').
The first of Ibn WÃÂá¹£il's histories is Taþrëkh al-á¹¢ÃÂliḥë ('The á¹¢ÃÂliḥë History'), a general history of Islam from the time of Muḥammad to the year AH 636/637 (AD 1239/1240). It was first dedicated to Sultan al-á¹¢ÃÂliḥ Najm al-Dën Ayyà «b sometime between 1244 and 1249, and then re-dedicated to al-MuÿaáºÂáºÂam Tà «rÃÂnshÃÂh after the death of al-á¹¢ÃÂliḥ in 1249. The second is NaáºÂm al-durar fi þl-ḥawÃÂdith wa þl-siyar, dedicated to Sultan Tà «rÃÂnshÃÂh (1249âÂÂ1250). The third is Mufarrij al-kurà «b fë akhbÃÂr Banë Ayyà «b ('The Dissipater of Anxieties on the Reports of the Ayyubids'), a history of the Ayyubids down to 1263 and his most valuable work for later historians. It was written at Ḥamàbetween 1272 and 1285. Although ending in 1263, it contains a reference to the battle of Benevento in 1266. It survives in four incomplete manuscripts, but the complete text can be reconstructed from these.
Ibn WÃÂá¹£il wrote two works on poetry. The Tajrëd al-AghÃÂnë (or Mukhtaá¹£ar al-AghÃÂnë) is a summary of the 10th-century KitÃÂb al-aghÃÂnë, a collection of poems performed at various courts. It was commissioned by the Emir al-Maná¹£à «r II during Ibn WÃÂá¹£il's later period at ḤamÃÂ. Three manuscript copies are known. He also wrote a commentary on a work on Arabic prosody by his teacher Ibn al-ḤÃÂjib. Two copies are known, but the work spawned a series of commentaries in the following century.
Although he received a religious education, Ibn WÃÂá¹£il's interest lay in the rational sciences. His only work on religion falls in the realm of kalÃÂm (speculative theology). This was the Mukhtaá¹£ar al-arbaÿën fë uá¹£à «l al-dën ('The Summary of Forty Questions on the Bases of Religion'), a commentary on a work by al-RÃÂzë. It has not survived. Ibn WÃÂá¹£il's scientific works were no more popular. No copies of his two works on astronomy and medicine have survived. His work on astronomy, Nukhbat al-amlÃÂk fë hayþat al-aflÃÂk, was dedicated to Tà «rÃÂnshÃÂh. His medical work was a summary of his teacher Ibn Bayá¹ÂÃÂr's al-Mufrada.
