Ibn al-Jawzi

Abū al-Farash ʿAbd al-Raḥmān ibn ʿAlī ibn Muḥammad ibn al-Jawzī, often referred to as Ibn al-Jawzī (Arabic: ابن الجوزي; c. 1116 – 16 June 1201) for short, was a Muslim jurisconsult, preacher, orator, heresiographer, traditionist, historian, judge, hagiographer, and philologist who played an instrumental role in propagating the Hanbali school of orthodox Sunni jurisprudence in his native Baghdad during the twelfth-century. During "a life of great intellectual, religious and political activity," Ibn al-Jawzi came to be widely admired by his fellow Hanbalis for the tireless role he played in ensuring that that particular school – historically, the smallest of the four principal Sunni schools of law – enjoy the same level of "prestige" often bestowed by rulers on the Maliki, Shafi'i, and Hanafi rites.

Ibn al-Jawzi received a "very thorough education" during his adolescent years, and was fortunate to train under some of that era's most renowned Baghdadi scholars, including Ibn al-Zāg̲h̲ūnī (d. 1133), Abū Bakr al-Dīnawarī (d. 1137–8), Sayyid Razzāq Alī Jīlānī (d. 1208), and Abū Manṣūr al-Jawālīkī (d. 1144–5). Although Ibn al-Jawzi's scholarly career continued to blossom over the next few years, he became most famous during the reign of al-Mustadi (d. 1180), the thirty-third Abbasid caliph, whose support for Hanbalism allowed Ibn al-Jawzi to effectively become "one of the most influential persons" in Baghdad, due to the caliph's approval of Ibn al-Jawzi's public sermonizing to huge crowds in both pastoral and urban areas throughout Baghdad. In the vast majority of the public sermons delivered during al-Mustadi's reign, Ibn al-Jawzi often presented a stanch defense of the prophet Muhammad's example, and vigorously criticized all those whom he considered to be schismatics in the faith. At the same time, Ibn al-Jawzi's reputation as a scholar continued to grow due to the substantial role he played in managing many of the most important universities in the area, as well as on account of the sheer number of works he wrote during this period. As regards the latter point, it is important to note that part of Ibn al-Jawzi's legacy rests on his reputation for having been "one of the most prolific writers" of all time, with later scholars like Ibn Taymīyyah (d. 1328) studying over a thousand works written by Ibn al-Jawzi during their years of training. As scholars have noted, Ibn al-Jawzi's prodigious corpus, "varying in length" as it does, touches upon virtually "all the great disciplines" of classical Islamic study.
