Ibn Hazm (384–456 AH / 994–1064 CE) was an Andalusian jurist, theologian, hadith scholar, and historian based in Cordoba, recognized as the principal exponent and systematizer of the Zahiri school of jurisprudence . He is best known for his legal compendium al-Muhalla bil-Athar and his comparative study on religions and sects, al-Fasl fi al-Milal wa al-Ahwa wa al-Nihal .
Lineage and Early Life
His full name was Abu Muhammad Ali ibn Ahmad ibn Sa'id ibn Hazm ibn Ghalib ibn Salih ibn Khalaf ibn Ma'dan ibn Sufyan ibn Yazid . His ultimate forebear in Islam, Yazid, was of Persian origin and a client (mawla) of Yazid ibn Abi Sufyan . The first of his family to enter al-Andalus was Khalaf ibn Ma'dan during the reign of Abd al-Rahman al-Dakhil, taking up residence in the village of Montíjar (منت ليشم) within the district of Niebla .
Ibn Hazm recorded in his own hand that he was born in Cordoba on the eastern side of the suburb Munyat al-Mughirah before sunrise on the final day of Ramadan in 384 AH (with an alternate report giving 383 AH) . He was raised in wealth and high social standing; his father, Abu Umar Ahmad ibn Sa'id, served as a vizier to the Amirid regent al-Mansur Ibn Abi Amir and his successor al-Muzaffar . During his childhood in the palace, he was taught the Quran, poetry, and penmanship by the palace women before undertaking formal scholarly studies around the year 400 AH .
Political Career, Education, and Zahirism
Ibn Hazm experienced the political turbulence accompanying the collapse of the Umayyad caliphate in Cordoba, enduring displacement and imprisonment . He served as vizier to the Umayyad caliph Abd al-Rahman al-Mustazhir bi-Llah and subsequently to Hisham al-Mu'tadd bi-Llah, but later retired completely from political administration to focus on scholarship and composition .
He studied under several prominent Andalusian scholars, including Ahmad ibn al-Jasur, Yahya ibn Mas'ud ibn Wajh al-Janna, Yunus ibn Abd Allah ibn Mughith, Humam ibn Ahmad, Abd Allah ibn Rabi' al-Tamimi, Abu Umar al-Talamanki, and Abu al-Khiyar Mas'ud ibn Sulayman .
In jurisprudence, Ibn Hazm initially studied the Maliki school, shifted to the Shafi'i school, and eventually adopted the Zahiri school founded by Dawud al-Zahiri . He developed and defended Zahiri doctrine, rejecting analogical deduction (qiyas), subjective opinion (ra'y), juristic preference (istihsan), blind following (taqlid), and causal rationalization (ta'lil), while restricting valid legal rulings to the explicit texts of the Quran and the Sunnah, as expounded in al-Ihkam fi Usul al-Ahkam .
Among those who transmitted from him were his son Abu Rafi' al-Fadl and the traditionist al-Humaydi, while the judge Shurayh ibn Muhammad al-Ru'ayni was the last to transmit his works via general authorization (ijazah) .
Controversies and Standing
Biographers praised Ibn Hazm for his vast erudition, sharp intellect, and memory across hadith, legal theory, history, and literature . Ibn Bashkuwal noted that he was the most widely learned scholar of Islamic sciences in al-Andalus . His followers in al-Andalus were referred to as the Hazmiyya .
His sharp polemical style and direct criticism of earlier authorities led to intense disputes with contemporary jurists . This prompted the remark attributed to Ibn al-Arif: "The tongue of Ibn Hazm and the sword of al-Hajjaj ibn Yusuf were twin brothers" . He also engaged in notable debates with the Maliki jurist Abu al-Walid al-Baji . Hostility from opposing scholars led local rulers to ostracize him, and al-Mu'tadid ibn Abbad, ruler of Seville, ordered his writings to be publicly burned .
Exile and Death
Banished by various local rulers, Ibn Hazm spent his final years at his family's estate in Montíjar in the rural district of Niebla . He died there on Sunday evening with two nights remaining in the month of Sha'ban in 456 AH (with another report placing his death in 457 AH), at the age of seventy-one years and several months .
